[imp] Error viewing HTML email

[Dan Wilson]

Update CVS-HEAD yesterday and today.  Started seeing the error yesterday.

When attempting to view an HTML email by clicking 'unamed' link in the 
headers, I get:

Fatal error: The script tried to execute a method or access a property of an 
incomplete object. Please ensure that the class definition mime_message of the 
object you are trying to operate on was loaded _before_ the session was 
started in /home/dan/public_html/horde/lib/MIME/Contents.php on line 242

Looks like this is being stored in a session variable?  I have 
session.auto_start = 0, so I'm not sure what the problems is here.
