Bug 250128

Application: dolphin (1.4)
KDE Platform Version: 4.4.4 (KDE 4.4.4) "release 2"
Qt Version: 4.6.3
Operating System: Linux 2.6.34-12-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
Dolphin randomly crashes. The frequency is low; I have only seen this twice and I use it frequently. The only pattern I have noticed is that Dolphin is open behind other application windows and the crash occurs when it becomes the foreground application (I click on it on the task panel).

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