-- Information about the crash:
Before a crash occured I've created a sidebar Panel, moved it several times, added 10 or so interface elements, resized the sidebar several times and so on.  I've noticed then that not all elements on the sidebar have refreshed properly after those manipulations.

-- Backtrace:
Application: Przestrzeń robocza Plazmy (plasma-desktop), signal: Segmentation fault
