Public bug reported:
Binary package hint: gdm
I'm using kerberized NFS mounts, and the gdm user has no business poking
them. Still I get a lot of log spam because gdm can't get a krb5
context. The reason for this is that it adds a monitor for $HOME/.face,
but can't get to it:

I don't think it should do that when IncludeAll is false, ie. it
shouldn't list previous users at all in that case (note that it doesn't
help even if I remove /var/cache/gdm/ contents..).
