Bug#711421: nfs-common: NFS4 mount with kerberos hangs forewer

[Michal Kašpar <michal@kaspar.in>]

Package: nfs-common
Version: 1:1.2.8-4
Severity: normal

Dear Maintainer,
After last update that should solve 705507 the rpc.gssd no longer
crashes, but mounting NFS share hangs forewer with syslog messages:
NFS: Registering the id_resolver key type
Key type id_resolver registered
Key type id_legacy registered
rpc.gssd[2059]: ERROR: GSS-API: error in gss_free_lucid_sec_context():
GSS_S_NO_CONTEXT (No context has been established) - Unknown error
rpc.gssd[2059]: WARN: failed to free lucid sec context

followed by:

nfs: server servername not responding, timed out

I use NFS4 with sec=krb5. Everything worked fine until Sid unfreeze,
after which I was hit by 705507.
