Description Frédéric Buclin 2016-01-13 10:31:12 UTC

Application: plasmashell (5.5.2)

Qt Version: 5.6.0
Operating System: Linux 4.4.0-desktop-1.mga6 i686
Distribution: "Mageia 6"

-- Information about the crash:
I installed Mageia 6 Cauldron in VirtualBox, and today Plasma crashes pretty frequently when using rpmdrake. Not sure this is related, though.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/i686/libthread_db.so.1".

Comment 1 Frédéric Buclin 2016-01-13 14:32:58 UTC

Note that I used Alt+Tab a lot to shift between apps. I wonder if this was too much for Plasma.

Comment 2 opensuse.lietuviu.kalba 2016-01-13 16:14:05 UTC

You can try workaround as in https://bugs.kde.org/show_bug.cgi?id=357895 : 
K > Settings > Configure Desktop (or System Settings) > Desktop Behavior > (Workspace), uncheck "Show Informational Tips"
