Bug ID: 361513 Summary: Crash when switching windows shortly after disconnecting HDMI 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 4.2.0-35-generic x86_64 Distribution: Ubuntu 15.10 -- Information about the crash: - What I was doing when the application crashed: Switching windows from Chromium to something else (I forget). A few minutes prior I had disconnected my laptop from HDMI (nothing unusual happened while I was watching a video with it). - Unusual behavior I noticed: The screen momentarily turned all black. Nothing looked strange after it lit up again. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
