Application: dolphin (2.0)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
I am running several virtual desktops.  When I moved to the one that had two dolphin windows open, one of them (the second instance) crashed, the only user-action being asking the window manager to refresh the window.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
