Summary: Crash when coming out of standby
Product: plasmashell
Version: 5.4.2
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: jessetalav...@aol.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.4.2)
Qt Version: 5.4.2
Operating System: Linux 4.2.0-34-generic x86_64

-- Information about the crash:
About half an hour ago, I put my laptop on standby. Then I woke up my laptop
