[Samba] Winbind dumps core after upgrade to 3.2.6

[François Legal]

Hello, 
I was running 3.2.4 since yesterday evening, when I decided to
upgrade to 3.2.6 

I did recompile from the sources (with the same configure options I
used for 3.2.4) then shutdown samba, replace the binaries and libs,
then start again. 

Everything then went fine until this morning when a user from a
trusted domain made a connection to the DC. I took a look and saw that
winbindd dumped core yesterday evening by the time I disconnected from
the machine
