Sometime when viewing emails in kontact, emails do not display in the bottom window for viewing despite single clicking on them. Single clicking on other emails will display them properly, but certain ones will not. When these certain non-displaying emails are double clicked on (in order to open them in a separate pop up window for viewing) Kontact crashes with the following output.

Which emails cause this behavior seem to be random. However, next time this happens I will try and find which email caused it on that occassion and paste the html of that email here in case something in particular is triggering it.

This is a fairly frequent problem, I encounter it about three or four times a day at the moment (with fairly heavy office use).
