I've had consistent problems with rpc.gssd segfaulting with krb5 NFS 
mounts ever since 6.1 came out -- actually, I haven't been able to find 
any way to use krb5-required NFS mounts at all since then (including 
with my own builds, though I didn't spent a lot of time on it yet -- 
maybe next week). I haven't had any trouble so long as krb5 wasn't 
required, so NFS has always been usable, just not done properly with 
Kerberos.

Are you saying that you can mount krb5 NFS with the 1.2.3-15 rebuild?
