Description rainer 2016-03-09 19:11:11 UTC

Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.3-1-default x86_64
Distribution: "openSUSE Tumbleweed (20160307) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I have a setup where I connect my monitor (HDMI) to two computers using a hardware switch. This computer was started with the monitor switched to it, I logged in with kdm and worked a little. Switching to the other computer (windows based), working there. Switching back here, already twice today I was greeted with the Crash dialog. It doesn't happen always, but frequently. Currently it seems to restart and work again all by itself.

The crash can be reproduced sometimes.

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

Comment 1 rainer 2016-03-09 19:17:15 UTC

It is the same system as in bug 358211, but a newer version of the plasma shell (so in a sense it rather supersedes bug 358211)

Comment 2 Martin Klapetek 2016-03-10 14:15:30 UTC

Thanks, I'll mark is as duplicate with newer version then.
