Description Kai Henningsen 2014-03-01 11:32:39 UTC 
Application: plasma-desktop (4.11.5)
KDE Platform Version: 4.11.5
Qt Version: 4.8.4
Operating System: Linux 3.11.0-17-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
I was trying to add the IRC Plasmoid to the task bar.

This also damaged the configuration of my second (vertical) taskbar, where the system load plasmoid was suddenly maximized.

Adding IRC to that taskbar instead worked, for some value of worked - the taskbar then thought it was at least twice as wide, leading to all the other Plasmoids being twice as wide and shown incorrectly. Took me a while to fix it all.

-- Backtrace:
Application: Plasma-Desktop-Umgebung (plasma-desktop), signal: Aborted

I just tried again.
Seemed to work, except I couldn't see the newly-added Plasmoid.
So I tried adding athe analog clock, so I might find where it was invisibly.

Crashed again, and system load again gobbled up all the free space.
