This is a known bug; it sometimes happens in large directories and has
to do with invalidation of cached directory information on the client.
There's a fix for this which I haven't committed yet because I thought
it was too slow in some cases, and a better fix is possible.

I might commit it anyway as an intermediate patch because it's been
lying around for too long now.
