Hi Maik,

many thanks for your quick reply.

Looking at the instructions to get a backtrace in Debian https://
wiki.debian.org/HowToGetABacktrace there are additional comments on pagination 
and multi-threaded appplications. I installed debug symbols before running gdb 
and then applied your commands above.

Please let me know, if that does not contain the relevant information.
