[Evolution] Could not parse MIME message

[Kenn Munro <kenn cyberbeach net>]

I receive some emails sent with Content-Transfer-Encode: base64 and
Content-Type: multipart/mixed.  When viewing them in Evolution, it says:
"Could not parse MIME message. Displaying as source."  And then it shows
the encoded stuff.

Is this behavior normal?  Is there any way to have Evolution decode
these and be able to view them inline or save them as an attachment?

I can save the encoded stuff to a text file and decode it manually using
mimencode -u.

I'm using Evolution 1.0.4.99 on Red Hat 7.2.

Thanks...
