There is something going wrong much earlier than this in the MDS session 
table.  Can you post/email the full log?  I fixed a few bugs in this area 
on monday, but didn't finish before leaving town for the week.

We'll do some testing of this and see if we can replicate the problem.

This doesn't sound like a bug.  The .snap directory is hidden by design, 
so you won't e.g. traverse into it when you do a 'du' or 'find'.  Even 
though you won't see it in a directory listing, you it's still there, and 
you can cd into it or mkdir .snap/whatever to create your snapshot.

Although probably, if you mkdir .snap, it should succeed, and thereafter 
'hide' the virtual .snap directory, so that we minimize the extent to 
which we break otherwise valid filenames.  IIRC that's what the netapps 
do with .snapshot.
