Description Bram Verhulst 2014-03-01 23:23:57 UTC 
Application: plasma-desktop (4.11.5)
KDE Platform Version: 4.11.5
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Linux Mint 16 Petra

-- Information about the crash:
KDE Plasma crashed after closing Ark. At the time there were 2 Ark-windows open, one containing the archive, another with the document I extracted from the RAR-file.

After multiple tries I cannot get this bug to reproduce.

The crash does not seem to be reproducible.

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

New crash information added by DrKonqi

plasma-desktop (4.11.13) on KDE Platform 4.14.2 using Qt 4.8.6

The same error appeared while closing Dolphin. At that time there were 3 Dolphin windows opened; the first one closed regulary, while the crash happened while closing the second one.
