If you delete your .msf for the corresponding newsgroup, does this work again?

Deleting the MSF seemed to fix it in this case. What would cause MailNews to get into this condition in the first place, though?

See bug 82595 for details. If you experience a crash again with this new .msf, please re-file. Thanks. *** This bug has been marked as a duplicate of 82595 ***

From 82595 - ------- Additional Comments From bienvenu@netscape.com 2001-05-25 09:19 ------- OK, here's the problem - when messages arrive out of threading order, we have to move messages around in the thread table in order to get the first message in the thread to be the first message in the thread table. The way we do this is, if we see that a new message is the parent of an existing message, we move it before the existing message. If the existing message was the former "first message in the thread", the new message becomes the first message in the thread. However, in this case, what's happening is that the newly arrived message is a parent of the soon to be former first message in the thread, but the newly arrived message already has a parent in the thread. What needs to happen is that the oldest existing ancestor of the newly arrived message should become the root message in the thread. In most cases, that will end up being the new message, but it might be an existing message. I'll try to come up with a patch for this. verified dup.
