Can you reproduce the problem by trying to answer on that mail again? Or has this happend only one time?

I haven't seen this expect for the one time.  If you want me to try something let me know.  But I haven't seen it happen since this time either.  I am guessing there may had been memory corruption some place and we just happened to crash here.  So the bt may not really be valid.

Well, kmail sometimes crashs reproduceable for me when opening or replying on certain mails. So reporting such crashes is perfectly "valid". 
But if you cannot reproduce your problem, no developer will be able to. So I'm closing this bug - it cannot be fixed. (Please don't mind the ugly word "invalid" :) )

OK, I have a reproducer now.  If you save the mail as something (Ctrl + S), but I did a right click and did the same option.  saved the email as /tmp/1.patch and then try to reply to the email afterwards and that will cause things to crash.  Restarting Kontact fixes the issue and allows me to reply, but if I save the email again then the crash reproduces every time I go through the steps.

Thanks! Confirmed. I can reproduce the crash now in KDE 4.3.3.

sweet!  I am now using 4.3.4 FYI.

can you please install kdepim dbg package and post a new crash log please ?

Here you go.  I am surprised you are unable to reproduce this on your own, it happens every time for me.  Let me know if you need anymore dbg info.
