Description Edward Oubrayrie 2015-04-01 20:47:03 UTC
Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 4.0.0-0.rc5.git4.1.fc22.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
Connecting/Disconnecting external HDMI screen

On the latest Fedora 22 beta, Plasma 2 + Kwin are overall very unstable when changing screen number (especially removing a screen):

* Sometimes KWin crashes (no way to report a bug  with a stacktrace yet, only an item in a fedora event log window with do-nothing buttons)
* Sometimes the disconnect is not detected
* Sometimes plasma AND krunner crash simultaneously (this bug seems to be the latter)

The hardware is Dell E7440 with latest A14 BIOS, if that matters.

I can provide more logs (I just don t know what is relevant). No duplicates were found by the tool, which surprised me as it happens quite often.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Attaching krunner s backtrace. It should probably be a separate bug, but it always happens simultaneously with the plasma crash above, so the cause may be common (and krunner "does not provide a reporting address", which is like the 5th bug I am writing about in this report... setting a new record I hope :D).

Application: krunner (krunner), signal: Segmentation fault

Even tough this seems Qt 5.4, the backtrace is identical to https://bugs.kde.org/show_bug.cgi?id=345173
