    <thetext>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: &quot;openSUSE Tumbleweed (20160422) (x86_64)&quot;

-- Information about the crash:
- What I was doing when the application crashed: I&apos;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&apos;m sure attach my information.
So even if it&apos;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.
