The only reason I use nss_wins is because logging into Active Directory
with pam_winbind.so doesn't seem to work if I don't.  Perhaps its not
able to resolve the AD servers?  I really never worried about it until
nss_wins started having problems.

I haven't noticed any other programs crashing, but I don't think I have
any other programs doing lots of name resolution.  This bug is pretty
elusive, so it might only show up in Firefox/Iceweasel which easily does
the most name lookups on my machine.

Thanks for the quick response.
