Hi!

I started getting such errors:

PHP Fatal error:  Call to a member function getMIMEPart() on a  
non-object in ../horde5/imp/lib/Mime/Viewer/Status.php on line 89,  
referer:  
https://server/imp/basic.php?mailbox=SU5CT1guVHJhc2g&page=mailbox&newmail=1&mpage=273

Horde/5.1.7/Imp 6.1.7,Horde_Mime 2.6.1, Horde_Mime_Viewer 2.0.8.
