Sorry, I didn't realize that you wouldn't receive the e-mail.

It seems to me that what we really need is to know what lines caused the 
crash.  Without that, what can be done?

The fact that it's not doing it on your computer will make it extra hard to 
diagnose.  I'm a little doubtful about this really going anywhere.  :)

If you want to submit it to the KMail devs, then yes, I would think so.  But I 
wouldn't send it without the problem config file lines too.
