Description of problem: When exploring app menu with the mouse, I manage to make plasma crash (black desktop/screen, except for already running applications) How reproducible: Every time ! Steps to Reproduce: 1. App menu > Tools > Emulators > Virtual box (or wine sub menu) 2. mouse jump on App menu > Recent apps OR App menu > Internet OR ... 3. after a sub second, plasma crashes before restarting itself https://bugs.mageia.org/show_bug.cgi?id=22117
Application: plasmashell (5.8.7) Qt Version: 5.6.2 Frameworks Version: 5.32.0 Operating System: Linux 4.9.56-desktop-1.mga6 x86_64 Distribution: "Mageia 6" -- Information about the crash: <see above comment> The crash can be reproduced every time. -- Backtrace: A useful backtrace could not be generated
To investigate the crash, we unfortunately need the backtrace. Please see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports for more information.
Created attachment 109607 [details] gdb backtrace I did attach gdb to plasmashell process from my user terminal, I got many many errors like in the ten first lines, then I needed to continue the interrupted process [(gdb) c] I made a jump in the menu, and then I got the line : Thread 1 "plasmashell" received signal SIGSEGV, Segmentation fault. following lines may give you clues. Let me know if it's not sufficient. At the end plasmashell has restarted itself, after a black desktop (with applications still running over)
Do not use 'c' (continue), but 'bt' to get the backtrace. If you try to continue running an already crashed process, things cannot get better :)
Any success with comment #4?
Created attachment 110274 [details] plasmashell gdb backtrace (c > "bug" > bt) hope this backtrace is good enough
Thanks! This is a Qt bug that's resolved in newer Qt versions. *** This bug has been marked as a duplicate of bug 369430 ***
