[Users] One of those mails which locks up Claws-Mail

[Liz Dodd]

I've just had one email lock up Claws-Mail. 
It's a text email.
I've run Claws-Mail with the debug flag and collected the output, and
viewed the offending mail with 'less'.

I really am not sure why this mail has stopped all Claws activity, and
left me with a white screen.

I am willing to share the full data with a developer if required.
This is the last 20 lines of the debug txt

I'll not try to remove the email yet, in case further tests are advised.

A second text email from the same sender was read with no difficulties.
