Hi, 
This error is not reproducable, but it happend several times to me. 
When I submit a large messages to a phpBB-style forum (like kde-form.org, or in my case: http://forum.nedlinux.nl ) Konqueror crashes immediatly when clicking on the [Ok] button to submit the message. The message itself however does arrive in the forum. 

This is the output of DRKonqi:
