segfault , had to re-mount

[Pooya Woodcock <pooya@xxxxxxxxxxxxxxx>]

Got this error on just one node (out of four)... not sure what  
happened. This was in glusterfs not glusterfsd. Going to try to find  
out what caused this. All I had to do to fix was restart the client  
glusterfs and it mounted fine.
