It still happens once in a while. It just won't expunge old messages 
from unseen. There is no other trace or log message.
I was hoping to isolate the cause, but all I could only say for sure 
that it happens sometime after Dovecot first starts up and I have to 
restart to fix it.
dovecot-virtual files look like this:
# cat virtual/all/dovecot-virtual
*
   all
# cat virtual/Unseen/dovecot-virtual
virtual.all
   inthread refs unseen
