xsession-errors

Thanks for the bug report! This crash has been reported already. So far, the root cause is unknown, but maybe your xsession-errors can give some clues - Thanks!

*** This bug has been marked as a duplicate of bug 208921 ***

Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-trunk-686 i686
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
I wanted to cut/paste a directory. In dolphin: cut directory, browse to mounted vfat, crash.
Nepomuk & Strigi were enabled (although strigi failed to initialize)

What I was doing when the application crashed:
Trying to reproduce the crash. Cut/paste of directory worked this time, randomly opening directories crashed dolphin again.

xsession-errors of third backtrace

Disabling Strigi (leaving Nepomuk enabled) resolves the issue.

Your original report and your comment 5 are bug 208921 which should be fixed in KDE 4.3.5 and later.

Your comment 3 is a different crash. If you upgrade to KDE 4.4 and you can still reproduce this, please open a new bug report about that issue. Thanks!

Thank you for your fast reply! I will wait for KDE 4.4 then.

ps: Comment 7 is incorrect, I also had to disable nepomuk.
