-- 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:
