Bug 231184

Application: dolphin (1.4)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.2
Operating System: Linux 2.6.30.10-105.2.23.fc11.i586 i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
I was doing a Nepomuk search in one Dolphin window (for "fundamental theorem of algebra", without the quotes).  While I was waiting, I opened another Dolphin window and started browsing.  Dolphin crashed and both windows disappeared.

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