I can not think that even the most cursory reading of my post can result in this answer.

Yes I do use a spam filter. No, I am not worried about its function.

I am highlighting (worried would be too strong a word) that a piece of spam manages to crash Evolution.

I do not think this should happen.

Running Evolution from commandline shows I had a segmentation fault.

Below is a backtrace from gdb:

I would hazard a guess it is because libwebkitgtk does not know how to handle the flash object.

If you want more information, please tell.
