Bug ID: 394367
Summary: Can't Add Taskbar Widgets while running Synergy-Core
as Server
Product: plasmashell
Version: 5.12.5
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: normal
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: ryaner...@mac.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.12.5)
Qt Version: 5.10.1
Frameworks Version: 5.46.0
Operating System: Linux 4.16.8-1-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- What I was doing when the application crashed:
On this system, I was running synergy-core --server, with one client attached.
When I click on the taskbar "menu" button or the "add widget" button Plasma
freezes.
Using `pkill5 plasmashell` then does not exit cause plasmashell to exit...
Must use `pkill -11 plasmashell`
I did this twice. However, after terminating both `plasmashell` and
`synergy-core`, the widget menu is still freezing up plasmashell...
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
