Hey folks,
since I've upgraded to Samba4 (4.0.6-1) i cant use it anymore. Every time a user tries to connect to it it crashes and i get a core dump.
Here is what journalctl -f prints on crash:

Jun 06 17:57:27 mymachine systemd-coredump[10710]: Process 10709 (smbd) dumped core.Has anyone ever experienced the same issue? Or can you give me a hint where to start?
The strange thing is, that after the upgrade from version 3 it worked like a charm. Then i restarted the machine, it also worked and one day later, from one second to the other, it stopped working.
Thanks in advance,

Same problem for me. The stacktrace is nearly identical. I asked in the irc channel #samba at freenode. But no response yet.
