Yes. Any chance you could send me that email? If you can't find it, you
can get to it quickly with binary search (e.g. assuming 100 mails):

1. disable fts-squat
2. use imap:

a login user pass
b select mailbox
c search 1:100 text hello (crash ->)
d search 1:50 text hello (no crash ->)
d search 51:100 text hello (crash ->)
..etc..
