   One of the two people who caused this assert has touched their
mailbox via POP (Qualcomm POP, I haven't switched my POP service
to dovecot yet).  The X-UIDL would have been added by either
qpopper or Eudora most likely.  People are warned not to do
POP and IMAP at the same time, but it happens anyway.
