Timo, I came into work this morning and found three new core dumps from 
maildir_uidlist_records_array_delete while running the patch you gave me 
yesterday, so I guess it's not fixed after all. I double checked that it 
is in fact running your patch, and it is. You can tell also that 
maildir-uidlist.c: line 403 changed to 405.

Here's the short backtrace:
