kde crash dump on kmail crashing because of the last search file.

Pasting the backtrace:

I have to CHANGE my report: I just got the same type of crash again (immediate crash at startup). I tried to just remove the search file, but it didn't help. So I traced again, and found, that the problem lies in the .kde/share/apps/kmail/imap directory structure. I'll attach the broken structure, although I believe you won't find the error easily: I moved those files away from the imap directory, and after that, kmail could start. I closed it and copied the broken structure back - but kmail could still start. But it doesn't remember how many mails there are in the folders - I have to click on every single one again to see the # of mails.

I also made a crashdump, and called kmail from the command line to see some error messages. Everything attached after this entry.

Still I'm not sure if it's the imap directory structure alone - there must be some other location of the problem also, as after the first successful start, even after copying back the broken structure, it did start up, but obviously ignored the contents.

I couldn't upload the broken imap directory structure, as its about 5MB - I put it on http://zmi.at/x/kmail-imap-structure-broken.tz2 (.tar.bz2)

Comment for that file:
broken imap subdirs that obviously made kmail crash. After moving them away, kmail started w/o error

I have had a similar problem -- but in my case the "broken structure" is somewhat simpler:  after an abnormal termination of kmail, I wind up with an empty file in ~/.kde/share/apps/kmail/imap, called "870628286".  Subsequently trying to start kmail leads to an immediate crash.  Removing this "870628286" file lets kmail start up normally, albeit with a few undesired side effects (all folders forget the message sort order, and the body of the message I was looking at right before the crash shows up blank, but can be resurrected by moving it to a different folder.)

This problem is new in KDE 3.5 for me.
