I followed Renés suggestion to produce a signal 11 internal error with 
rpcclient (Thanks). It worked, but I'm not shure it's the same reason 
causing this error. Backtrace is appended. Panic action is still set to 
catch the original error.

I also rebuild samba from source without suse patches and tried the same 
action. It produced the same error.

Thanks
