Your libkscreen is old. Tell the opensuse people to update it.

openSUSE 13.2 has libkscreen 1.0.5+kscreen 1.0.71. Is there a newer release?

1.0.5 should be fine. Marek can you install libkscreen debug pacakge and attach the backtrace with more symbols? Also make sure you have 1.0.5 of libkscreen

I have libkscreen 1.0.5-1.1 installed. The libkscreen debug pacakge is not offered in my yast software managmentI for opensuse 13.2..  I should know the exact name of this package (including version) and where to find it (I browse internet, several versions were offered in source form, none precompiled; web description told debug but packages did not include "debug" in their names, only libkscreen, so I hesitate to install them). Also it is not clear me if the debugging is automatic after installation or something must be adjusted.

Additional information which I figured out after reporting the problem:
It occurs because I work with the PC in play as a remote server.
I connect to it via ssh by an older PC with suse linux 8.2 installed. And
it makes this problem (crashes). When I work with the server locally, okular
works fine. Other X-applications via this connection works, only
displaying is rather slow (e.g., konqueror, yast2, gv). Yast2 works but
writes this error message "libGL error: failed to load driver: swrast".
I do not know if this is related to our problem, I list it here
for completness. When I connect with the older PC to my notebook with
opensuse 13.1 installed (server has 13.2), okular does not crash.

Then it is a kscreen bug, related to bug 331537, indicating it fails to find xrandr information on remote displays.

Please ask in a forum of your distribution which packages you need to install for debugging symbols in this case.

I installed okular-debuginfo-4.11.0-2.1.x86_64. However the backtrace log did not improve.

Here is the output in the terminal:

Got object file from memory but can't read symbols: File truncated.

I do not know how to continue.

You installed the debug packages from a different repository or from a different version in the same repository.

I have okular-4.14.3-4.2.x86_64. I installed okular-debuginfo-4.14.3-4.2.x86_64.
Here is the backtrace:

As a stop gap measure you can try removing KSC_XRandR11.so
