Description Marián Konček 2023-09-08 06:07:58 UTC

SUMMARY
Crash happens without a notification. No backtrace available.
I am running Fedora 38, KDE, Wayland. I have multiple instances of Dolphin on virtual desktops. When I unplug the Thunderbolt plugin, the screen rearranges, but no crash happens. After plugging the Thunderbolt back in, *a single* instance of Dolphin exists with no crash notification.
I tried executing Dolphin from a terminal to see if I could get some standard output, but that instance did not crash.
On my docking station I have: mouse, keyboard, Jack headphones, Ethernet, 2 external monitors and the laptop monitor is set to be disabled.

There is a typo in the Description, should have been:
```
*a single* instance of Dolphin exits with no crash notification.
```

Output of journalctl -f

Adding the output of journalctl just before plugging the Thunderbolt in.

Hi! Thank you for your bug report. If you can reproduce this issue, could you try obtaining a backtrace with debug symbols?

Comment 5 Marián Konček 2023-11-13 08:13:01 UTC

The crash reporting daemon does not catch this crash for some reason. I downloaded the debuginfo packages and ran Dolphin in gdb. I will keep the stopped process running for as long as possible, so you can ask about variables and so...
