Description Markus Grabner 2011-05-03 22:41:51 UTC 
Application: konqueror (4.6.00 (4.6.0) "release 6")
KDE Platform Version: 4.6.00 (4.6.0) "release 6"
Qt Version: 4.7.1
Operating System: Linux 2.6.37.1-1.2-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
I tried to print a web page as a PDF file and opened the file dialog to choose a location. When browsing to the desired directory, the application crashed. I did this many times before without problems, and tried it a second time after the crash (with success).

The crash does not seem to be reproducible.

-- Backtrace:
Application: Konqueror (kdeinit4), signal: Segmentation fault

*** Bug 273457 has been marked as a duplicate of this bug. ***
Comment 2 Christophe Marin 2011-05-18 12:21:02 UTC 
If the crash can be reproduced every time, please install the kdelib4-debuginfo and kdelibs4-debugsource packages to get a better backtrace.
Comment 3 Markus Grabner 2011-05-19 00:37:41 UTC 
I did so, but now I can't reproduce the bug. It seems to depend on some other condition which was reset at reboot. When the problem occurs again, I'll post another backtrace.
