Package: samba
Version: 2:4.1.4+dfsg-3
Severity: grave
Justification: renders package unusable

Hi,

I just updated to the latest samba4 version and since then, none of my shares can be accessed anymore without samba crashing.

This is the stack trace I got out of the log files:

Unfortunately, samba is pretty much useless with this bug. It doesn't matter whether the phsyical location of the share is on an mdraid or on /dev/sda1 (/ partition).
