Description Tobias 2017-07-02 09:47:25 UTC

Application: plasmashell (5.10.2)

Qt Version: 5.9.0
Frameworks Version: 5.34.0
Operating System: Linux 4.11.8-1.g42bd7a0-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
This has been reportet for Plasma 5.9.x before, but it still happens to me after updating to 5.10.2

- What I was doing when the application crashed / Unusual behavior I noticed:
During normal usage of KDE (but mostly after a longer time -approx 20 minutes- of user inactivity) Plasma widgets disappear and the screen turns black while windows of running applications remain. You can still start programs with keyboard shortcuts. To get back to normal Plasma shell you need to kill X and restart it.

I have turned off any power management at boot.

The crash can be reproduced every time.

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

Comment 1 David Edmundson 2017-07-02 14:55:34 UTC

>The crash can be reproduced every time.

Can you install debug symbols for QtBase and reproduce this please.

Then reset the bug status to unconfirmed.

Comment 2 Tobias 2017-07-04 19:44:49 UTC

Created attachment 106441 [details]
Plasmashell crash report w/ qtbase + plasma debugsymbols

Comment 3 Tobias 2017-07-04 19:47:45 UTC

After some repo updates to Plasma 5.10.3 and Qtbase 5.9.0-2.1 the same issue still occurs.

I've created the attached report after installing Qtbase and Plasmashell debug symbosl.
