I build with some debugging information, but sources weren't available since I installed this as part of Gentoo's KDE packages. 

There appears to be some kind of folder activity just after I enter my password and just before the crash.

Comment 1 Justin Randall 2004-03-10 05:00:11 UTC

This also happens with the latest version in CVS, same callstack. More info: it is failing when deleting removedItem in frame #6. The next address on the callstack indicates something is getting trashed. 

Also worth noting: Running the CVS version didn't take me immediately to my imap folder. The crash doesn't occur until my IMAP inbox folder is opened AND an item is being removed from the message list.

Comment 2 Justin Randall 2004-03-10 05:24:37 UTC

Stepping through the code, it's the second call to KMHeaders::msgRemoved() that causes the crash.

It may be worth noting that I have enabled, then disabled message threading, though messages still appeared to be threaded. From another workstation (at work), I read and deleted some email. KMail started crashing when I returned home.

To workaround the problem, I selected "cancel" when prompted for a password, then re-enabled "thread message headers" in the "configure kmail" "appearance" section.

I think these are the steps to reproduce:
1. enable message threading under "settings->configure kmail->appearance->headers"
2. disable message threading
3. login from another location
4. delete some threaded messages
5. login from the original location
6. open folder
