OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: orakmoyaoffic...@gmail.com

-- Information about the crash:
I'm seeing intermittent crashes of plasmashell without an obvious cause.
Seems to be random. I'm seeing it happen once or twice within 10 minutes.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = <optimized
