Description Markus Hinkelmann 2010-02-19 17:07:04 UTC
Application: dolphin (1.4)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.1
Operating System: Linux 2.6.31-20-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
dolphin crashed immediately on startup with a segfault.
There are no samba shares in my network, but /home is mounted by nfs.
While starting dolphin nepomuk/strigi/virtuoso were running on heavy load.
A comparable crash has occured to me only once since KDE 4.4.0 . I use kubuntu 9.10 with packages from the backports repos.

The crash can be reproduced some of the time.

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

Comment 1 Peter Penz 2010-08-08 13:32:41 UTC
Thanks for the report. Does this issue still occur with a more recent KDE version in your environment? I could not reproduce it here with KDE SC 4.4.2 and KDE SC 4.5.0.
Comment 2 Julian Steinmann 2018-03-14 11:34:12 UTC
Cannot reproduce either. Closing, please reopen if you still experience this behavior with Dolphin 17.12.3.
