Two problem Email messages

We are starting to have issues with certain incoming Email messages causing
Claws to freeze for several seconds and then crash.  Because the offending
message remains in the user's incoming /var/spool/mail/$LOGNAME file, when they
restart Claws, it will start processing the mailspool again (re-importing all
the messages again) and then freeze and crash again when it hits the offending

This is a major problem because if a user gets such a message, they can no
longer use Claws until a sysadmin goes in and manually parses out all the Email
in their mailspool and tries to import each message, one-by-one, until the
offending one can be identified.  This is very time consuming.

We are using Protocol: Local mbox file

I have two such messages that will crash Claws, even the most current version
of Claws.  I sanitized them slightly by changing all from address domains to
"nospamfrom" and the to address domains to "nospamto" and wiping phone numbers
and such.  The two messages are not from the same person or same domain, and
separated by more than a month.  The only thing they seem to have in common is
that the mail agent is MS Outlook and they have a plaintext part and TNEF part.
 But none of that is unusual, we get such Email all the time with no problems.

I am attaching the two problem Email messages to this bug report.  To use them,
simply cat one of them into a test user's incoming local mbox file then click
on "Get Mail" and Claws will then freeze and crash.
