Bug 798633

Description of problem:
Created a distributed-replicate volume, on the fuse client was running dbench. The client got crashed after sometime at mdc_lookup. so remounted the client.
From a nfs client, started doing rmdir on the dbench created directories. This caused a crash on the nfs server.
Bug id: http://bugzilla.redhat.com/show_bug.cgi?id=798608

Subsequently crashed a glusterfs brick.
