Subject: After upgrading to 3.4.3-1 winbind segfaults many time per second.
Package: winbind
Version: 2:3.4.3-1
Severity: important

Below is what I am experiencing after upgrading to 3.4.3-1.  It appears isolated to winbind,
as another site not using winbind works flawlessly.  Mailbox messages were flooding in faster
than I could delete them.  It seems to have a problem with getting group info from the DC.
