Application: systemsettings5 (5.2.2) Qt Version: 5.4.1 Operating System: Linux 3.19.0-15-generic x86_64 Distribution: Ubuntu 15.04 -- Information about the crash: Opening this section 'Created Shortcuts' is extremely slow. After setting one up and clicking Apply there is another hughe wait and regularly a crash. Similar happens when trying to add such a hotkey through the Kicker menu editor, it is likely to crash. If no crash there is still a good chance the new keys are not retained. This is a fresh install of the new release. The crash can be reproduced sometimes. -- Backtrace: Application: Systeeminstellingen (systemsettings5), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

I can add it happens with nVidia drivers version 340 & 346, there is no problem using version 304 or Nouveau. The problem manifests itself by no longer being able to use the previously while on Nouveau made Global shortcuts/hot keys, when logging in with the above mentioned nVidia drivers the shortcuts will work for about a minute and then fail. Subsequent editing of them often results in a crash of System Settings. Also, shutting down now becomes an exercise in patience, between clicking on the shut down or restart button and the system actually going down is a wait of some two minutes. I have done a fresh install and the same happens.
This bug affects me as well. I am using Nvidia binary driver 346 b/c the Nouvea driver sux; it can not display an external monitor properly. I am using Kubutnu 15.04, and that I do not see the desktop panel once I've logged in to the desktop. Here is the output of dmesg, and it shows that probably a kwin process was dying. The error is: [ 777.740929] QXcbEventReader[3966]: segfault at 7f1ff1d68099 ip 00007f1ff1d68099 sp 00007f1fe4200e60 error 14

I've set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved" when you respond, thanks.

I am not sure what date this persistent crash happened and was reported but presently (QT 5.12.8, Gwenview 19.12.3) there is no problem. At the time the remedy was to purge Gwenview and reinstall.
