[horde] Interface 'Horde_Mime_Headers_Extension_Mime' not found but it is there

[Paul Griffith]

Hi,

   I have run into a issue with Horde. Here is the error message I get.

---snip---
A fatal error has occurred
Interface 'Horde_Mime_Headers_Extension_Mime' not found

1. Horde_ErrorHandler::catchFatalError()

Details
The full error message is logged in Horde's log file, and is shown below 
only to administrators. Non-administrative users will not see error details.

                 )

         )

Yet I have the Horde_Mime package installed

pear -c /local/horde/pear.conf list -c pear.horde.org | grep -i Mime
Horde_Mime             2.8.0   stable
Horde_Mime_Viewer      2.0.8   stable

I can force a re-install of Horde_Mime, but I get the same results. Any 
pointers?
