Description Paul Worrall 2024-05-28 10:06:50 UTC

Application: dolphin (24.05.0)

Qt Version: 6.7.1
Frameworks Version: 6.2.0
Operating System: Linux 6.9.2-arch1-1 x86_64
Windowing System: Wayland
Distribution: Arch Linux
DrKonqi: 6.0.5 [CoredumpBackend]

-- Information about the crash:
Under "Configure > Context Menu", enable the Bazaar plugin and click OK without first clicking Apply
Also crashes when disabling
Also reproducible with Git plugin
If I click "Apply" instead of "OK" I get a message about needing to restart Dolphin, and no crash occurs.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault

Thank you for the bug report! Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong:


#5  0x00007a1ac040974b in ??? () at /usr/lib/qt6/plugins/styles/breeze6.so
#13 0x00007a1ac96d56b6 in ??? () at /usr/lib/libKF6WidgetsAddons.so.6

#32 0x00007a1ac85f9554 in ??? () at /usr/lib/libQt6Gui.so.6

Could you please install debug symbols and attach a new symbolicated backtrace generated by using `coredumpctl gdb` in a terminal window? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl for details about how to do this. Thanks again!
