DrKonqi analyzes this part and I believe it works correctly. There is no
indication of main() or clone() being called at the bottom of the stack and
there is also frame #21 from threadweaver that has no symbol. To me it looks
like it hasn't loaded krunner's debug symbols. This could be maybe because you
upgraded krunner while it was running and the debug symbols don't match. It
could also be stack corruption or some bug in gdb. In any case, the backtrace
is useless. Drkonqi's parsing works correctly. This is all it can do, parse the
backtrace.
