Bug ID: 388684
Summary: Plasma crashes if screenshot notification disappears
while drag-'n-dropping image
Product: plasmashell
Version: 5.11.4
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: dakota.sulli...@madwiremedia.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.11.4)
Qt Version: 5.9.3
Frameworks Version: 5.41.0
Operating System: Linux 4.10.0-42-generic x86_64
Distribution: KDE neon User Edition 5.11
-- Information about the crash:
- What I was doing when the application crashed:
I had just taken a screenshot and was trying to drag-and-drop the image from
the notification into Slack, but apparently I took too long and the
notification timed out and disappeared, along with Plasma.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
