Hi Peter,
unfortunately I'm still unable to reproduce it, I believe it's due to the
configuration. The problem itself might be due to the header cache or some other
reason, do you mind sending me the output of bt full on the corefile?

Feel free to send it privately if you want.

Additionally, if you could devise a minimum set of ocnfiguration (i.e.: a
minimal .muttrc) that I can use to reproduce this bug, it will be great and it
will ensure that I will be able to fix it quicker :)
