Bug 257531

Application: dolphin (1.5)
KDE Platform Version: 4.5.3 (KDE 4.5.3) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.35.4 x86_64

-- Information about the crash:
Dolphin crashed without any user activity (even another desktop was activated at the moment). But Nepomuk indexing routines were heavily working. Perhaps it affected Dolphin in any way.

-- Backtrace:
Application: Dolphin (kdeinit4), signal: Aborted
