Description Alexandre Pereira 2016-05-13 16:42:34 UTC

Application: plasmashell (5.6.90)

Qt Version: 5.6.1
Frameworks Version: 5.22.0
Operating System: Linux 4.5.3-1-default x86_64
Distribution: "openSUSE Tumbleweed (20160511) (x86_64)"

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

I was simply switching activities with keyboard shortcuts ( next activity shortcut ). The activity switcher sidebar appeared and i noticed that an activity was missing. Right away plasma crashed.
When restarted, it showed all activities and didn't crashed again.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault

Comment 1 Ivan Čukić 2016-07-18 19:17:38 UTC

This should be OK now - Plasma 5.7.2 (to be released tomorrow) and master (5.8).

If it shows up again, please reopen this report.
