Segmentation fault with IMAP/"The message index is incorrect. Try reopening the mailbox."

[neteler]

Mutt regularly crashes for me. I am using an IMAP box (Microsoft IMAP server), in parallel also thunderbird is listening to auto-filter selected messages into IMAP folders. This happens:

---Mutt: imap://neteler@ntmail/INBOX [Msgs:1126 New:169 30M]---(reverse-date-received/date)------(3%)---
Sorting mailbox...
---Type <return> to continue, or q <return> to quit---

[brendan]

Can you reproduce this with 1.5.16?

[neteler]

A first test with 1.5.16 gives following message after less than 5 minutes:

The message index is incorrect. Try reopening the mailbox.

With CTRL-Z I can still get back to the command line and kill the mutt process :-(

[neteler]

Forgot to mention that after this message

The message index is incorrect. Try reopening the mailbox.

mutt is actually frozen.

Also segfault confirmed...:
