Yes, the working copy is already updated, but you need to tell what 
happened to monotone. Baz (via Tailor) reports only a rename from 
statistics to statistics/squid, which fails if executed directly.
If this rename makes sense, as Nathaniel says, then perhaps it must be 
broken in two or more operations to make it accetable to monotone.
I see two alternatives:
 - mtn drop statistics + mtn add statistics/squid (implicitly adding 
the directory statistics)
 -mtn rename statistics temp, mtn rename temp statistics/squid (again 
adding implicitly the new directory statistics)
Since baz said "rename" the latter solution seems better, but might be 
difficult to implement in Tailor.
Note: Tailor currently does nothing of the above: if the source backend 
says "rename a to b" it tries to execute exactly this operation.

The monotone backend for tailor skips explicit directory addition 
exactly to avoid this problem.
