Login. Try to display a message that is generated by a FritzBox (Subject:

A white page shows up (Imp crashes).

I am very sorry that I can not provide the culprit message here but I have
to repect the privacy wishes of my customer.

Problem seems to occur while processing a mime/related part. My "fix"
(patch) for this is appended below. I am very sorry for not providing more
input, if this information is too sparse please feel free to close the bug
report and curse about incompetent users right now. The MIME message may
as well be broken. 

I just want to give you guys a chance to have a look at this, maybe you
can judge by the patch if this is important or not.
