Application: plasma-desktop (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-13-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
I was on desktop no. 1 and have configured to open Geany via the application window setting (forced open on deskto no 2) to be opened on the other desktop. Then the Plasma desktop crshed. Probably this crash is related but I am not proficient enough to differentiate this: https://bugs.kde.org/show_bug.cgi?id=324218

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
