Bug 303957

Application: dolphin (2.0)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-26-generic-pae i686
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I have opened a folder in Dolphin and than moved to Google Chrome for browsing. The Dolphin window is not active. I don't remember it's minimized or restored or maximized.
But after some while browsing in Google Chrome, I suddenly see crash message. This happen two three times in past so I am posting this bug report.

The crash can be reproduced some of the time.

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