Backup and Recovery causing applications using Qt5 DLLs to crash
I'm a software engineer at Tableau Software and we've discovered a bug in Dell's Backup and Recovery software that is causing any 64-bit application which uses the Qt5 core DLLs to crash whenever a Save or Open file dialogue is opened. We have been able to reproduce this behavior with an extremely simple application using just QT code:
#include
#include
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QFileDialog::getSaveFileName();
return 0;
}
This app was built in Qt Creator with the standard Qt 5.4.1 SDK for 64-bit MSVC2013.
To work around this problem we are having to instruct our customers to completely remove the Backup and Recovery software from their workstation.
I have been unable to identify a good way to report this bug to Dell outside of this forum. Could someone point me in the right direction?

We had the same problem in our application and realized that only version 1.8.1.71 is concerned and it sometimes come pre-installed on some PCs.
Version 1.7.5.64 did not use Qt yet and in version 1.9.2.8, they removed the dependency in the shell overlay DLLs.
So upgrading DBaR is enough to workaround the issue.

We are software developers too. Our program has same issue on several new laptops.
Reported it to DELL today via telephone to the pro-support team.
A search of the internet reveals other programs that have same problem.

Thank you, EFSGRAHAM, for reporting this to Dell! It is very much appreciated as I'm having issues regarding this, it seems several others are, as well!
I hope you were successful in getting the Dell team to 'hear' you regarding this issue!
All the best to you!

This is a big "thank you", PT_TABLEAU, for posting this.
I've been having issues with my Dell desktop Windows 8.1 Pro 64 bit ... and the Dell Backup and Recovery application. Specifically had error codes pop up RE the Qt5 Core DLL after upgrading to Windows 10 Pro (upgrade done yesterday via IS0 file). This is a new computer purchased end of July 2015. It arrived with Dell Backup and Recovery version 1.7, which I finally updated to version 1.8. More stuff been going on that is pertinent to the issue, but will try to keep this short.
Sure hope Dell pays attention to your findings and addresses. And, I hope the poor Dell Customer Service Reps are informed about this ... it's miserable for everyone when the people who are supposed assist with various technical issues are not informed ... which leaves 'everyone' vulnerable to unresolved issues and/or escalating problems. Not fun!!!
Good luck to you in your communication with Dell ... and to all who are having issues due to this!

Dear Dell,
My name is Frank DeLise, senior director at Autodesk. Several of our tools use QT and this issue is affecting many of our customers, causing product crashes. Please let us know when this issue is resolved so we can alert our customers

Our product PortraitPro has had sporadic complaints from customers that it would crash when the file dialog was opened, yet we had never been able to reproduce the problem. Many thanks PT_TABLEAU for providing the answer!
The only solution we had been able to give our customers up until now was to suggest they use the 32-bit version of the software that does not have this problem.
I would also urge Dell to fix this problem urgently, since our support staff will now be told to suggest to customers with this problem that they uninstall Dell's Backup and Recovery software.
It is possible to fix this problem by just unregistering the shell extensions that cause it. This can be done by running the following commands as administrator:
regsvr32 /u "C:\Program Files (x86)\Dell Backup and Recovery\Components\Shell\DBROverlayIconBackuped.dll"
regsvr32 /u "C:\Program Files (x86)\Dell Backup and Recovery\Components\Shell\DBROverlayIconNotBackuped.dll"
regsvr32 /u "C:\Program Files (x86)\Dell Backup and Recovery\Components\Shell\DBRShellExtension.dll"
Qt seems to know about this problem, but say that the solution is not under their control:
https://bugreports.qt.io/browse/QTBUG-41416
However, the problem is caused because these shell extensions are also using Qt5. It should perhaps be made more clear that developing shell extensions using Qt is not a good idea, unless Qt is configured using the -qtnamespace as described in one of the answers to that bug report.

Dear Dell support,
I am the principal developer of the PixInsight image processing platform and CEO of Pleiades Astrophoto, a Spanish software development company. Our main application uses Qt 5, and many of our users working on Dell workstations and laptops are being severely affected by this problem. Please inform us when you have a solution to this issue.

We are also recommending all our users uninstall Dell's utilities, given that Dell is not resolving this issue. Unpresentable to say the least.

This is causing problems with Wireshark as well. Until the issue is fixed or we can find a workaround we'll have to recommend that people uninstall DBAR.

We are also seeing this issue with our main software. We are advising our customers to disable the shell extensions/overlays or simply remove the Dell Backup and Recovery Software.
Why has Dell not addressed this issue? Not even a "thanks for letting us know, we are working on it.".....
Oh, yeah, its because it is Dell.
