Description Bruno Friedmann 2016-05-03 18:44:15 UTC
Application: plasmashell (5.6.90)

Qt Version: 5.6.1
Frameworks Version: 5.21.0
Operating System: Linux 4.5.2-1-default x86_64
Distribution: "openSUSE Tumbleweed (20160422) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: I've started my plasma5 session and let it running alone. The screen goes to sleep after a half hour, and the locking happened normally.

Once wake up, and login I discover this crash in the tray icon.
btw drkonqi was not able to select 2 similar (now hidden) opened bugs 362552 and 362184 even if I click I'm sure attach my information.
So even if it's the wrong place to complain about drkonqi, someone need to take care of it.

During the starting session there were another crash (seen with coredumpctl) containing
warning: core file may not match specified executable file.
