Emails with attachments result in error message: Expected ';', got "text"

I searched for the error text, but found nothing. I have a co-worker who uses a different android phone and has Maildroid installed and he gets the same error. It is not on every message with an attachment, but occurs more than occasionally. The attachment in most recent experiences were pdf files. I can go to the standard Droid email and retrieve the message just fine.
