Description Toure 2015-09-24 13:49:07 UTC

Application: plasmashell (5.4.1)

Qt Version: 5.5.0
Operating System: Linux 4.2.1-300.fc23.x86_64 x86_64
Distribution: "Fedora release 23 (Twenty Three)"

-- Information about the crash:
- What I was doing when the application crashed:
I am running fedora 23 custom kde spin and I have had a problem when docking my laptop the panel will migrate to the external monitors and the only way I know to fix this is to delete the panel and create a new default panel on the laptop screen. After doing so I notice that plasma will crash and hence the filing of this bug.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
