I didn't have all dbg-Symbols installed, following https://wiki.ubuntu.com/Backtrace I gave it another try. Please see the attached full backtrace by dbg. Still I didn't understand how to pass the "--sync" option or to run it in the GDK_SYNCHRONIZE environment. If anybody can tell me how to do it I'm willing to try. If anybody knows how to further debug it, please tell me -- I'm happy to help to get this solved.
