inotify_rm_watch() failed: Invalid argument ?

I'm seeing these in my log:

should I worry? Kernel 2.6.22.1 and dovecot 1.0.x hg
checkout.

It probably means that you had one session running IDLE in a
mailbox,  
and another session deleted the mailbox. It's a bit stupid
that  
inotify_rm_watch() gives that error when it loses the
watched file. I  
already made it ignore this error in v1.1 code. I suppose I
could  
ignore it for v1.0.3 as well. http://hg.dove
