Procmail does seem to be a common denominator, don't know if it's 
coincidental or not.  The same happens to us, some users have folders that 
procmail shouldn't have been delivering to.  It happens when the user is 
deleting, but I'll be damned if I can pin it down further because I have 
not yet been able to duplicate.
