Description Alexander Blesius 2013-01-11 10:28:23 UTC

Application: okular (0.14.3)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-35-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:

extracting a page from a set of pages to print only this one to a new document called 'print.pdf'. When I tried to enter the directory path, Okular crashed. The problem hasn't occured again yet, though I tried it two more times.

The crash does not seem to be reproducible.

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

The top part of the backtrace

#7 0x00007f200c460566 in QFactoryLoader::instance (this=<optimized out>, key=...) at plugin/qfactoryloader.cpp:276
#8 0x00007f200cf1ad32 in QIcon::addFile (this=0x59548b8, fileName=..., size=..., mode=QIcon::Normal, state=QIcon::Off) at image/qicon.cpp:843 

is the same than described at https://bugs.kde.org/show_bug.cgi?id=298091 and in it the ?? point to libdbusmenu-qt.so.2 ( that is https://launchpad.net/libdbusmenu-qt )

That code is outside the scope of Okular. I'd suggest you to go there and file a bug about it, but if you don't really have a way to reproduce the crash it's going to be very hard that anyone actually can fix anything.

Sorry that my answer is not that much satisfactory and thanks a lot for caring about Okular and reporting this bug :-)
