Do you get the crash dialog? If yes, please add the backtrace as a comment. For more information, please see https://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

Comment 2 Albert Astals Cid 2015-03-12 23:07:08 UTC

Waiting for backtrace

Comment 3 Oliver Sander 2015-03-13 05:35:05 UTC

Is the following sufficient, or should I additionally install the Qt debugging symbols?

The crash is reproduced easily on current git master compiled against Debian Jessie.

I don't have the backtrace because manjaro do not compile applications with debug symbols.

Comment 5 Simone Gaiarin 2015-03-13 15:19:50 UTC

Ok. I've downloaded okular from the git repository and compiled it with:

cmake .. -DCMAKE_INSTALL_PREFIX=/mypath -DCMAKE_BUILD_TYPE=debugfull
make

This is the trace I get when the crash occurs.

It seems still unuseful. Is okular actually running the code in the test prefix where I've installed it or it's running code from /usr where my main system is installed?
I see that there are not debug symbols from the component /usr/lib/kde4/okularpart.so (which appear to be called from /usr).

I'm sorry but I'm not experienced with trace generation.

I think that my trace doesn't add anything to the one already provided by Oliver, but I wanted to try to generate a trace.
