[Pkg-samba-maint] Bug#763744: samba: Huge number of samba panic messages

[Santiago Vila]

Package: samba
Version: 2:4.1.11+dfsg-1
Severity: serious

Since I upgraded to jessie, I am literally being *spammed* by samba
panic messages (I have received more than 200 in an hour).

Here is a backtrace:

BTW: I see that there is available a new upstream release of samba:

http://www.samba.org/samba/history/samba-4.1.12.html

and the changelog says:

o  Fix smbd crashes when filename contains non-ascii character (bug #10716).

This could be the same bug, but I don't know. As this might be not
easy to debug, feel free to consider this bug as "please package
version 4.1.12" instead.

Thanks.
