Description Jon Nelson 2009-07-11 15:22:31 UTC 
Application that crashed: okular
Version of the application: 0.8.90
KDE Version: 4.2.95 (KDE 4.2.95 (KDE 4.3 RC1)) "release 139"
Qt Version: 4.5.2
Operating System: Linux 2.6.27.23-0.1-default x86_64
Distribution: "openSUSE 11.1 (x86_64)"

What I was doing when the application crashed:
I tried to print, it hung (unresponsive) after control-p with no dialog.
I restarted cups and that is when it crashed.


 -- Backtrace:
Application: Okular (okular), signal: Segmentation fault

This probably is http://bugreports.qt.nokia.com/browse/QTBUG-10512 and should be fixed in Qt 4.6.3. If you can still reproduce with that version, please file a bug report to http://bugreports.qt.nokia.com/
Comment 3 Christian Trippe 2010-08-09 08:49:50 UTC 
JFYI: Bug 242472 which in the end was marked as duplicate of this bug happened for me with Qt 4.6.3. I filled an upstream bug report at http://bugreports.qt.nokia.com/browse/QTBUG-12748

I experienced a very similar crash with Okular Version 0.16.2
Using KDE Development Platform 4.10.2. Should I file a new report, or ask for this one to be re-opened?
