Sentry Crash Report:

Description javaquemarti 2017-02-09 21:14:00 UTC

Application: plasmashell (5.9.0)

Qt Version: 5.7.1
Frameworks Version: 5.30.0
Operating System: Linux 4.9.7-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:

I have the new 5.9 widget "global menu" for the menu of windows. Almost every time I change the activities by pressing META+TAB, plasma crashes. I think it happens when the change of activity implies a change of window focus. I have not notice it happened when I use the activities button and menu.

The crash can be reproduced every time.

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