applications menu empty

[Ryan James]

after updates from the 4th or the 5th, my applications menu has been
empty. running update-desktop-database parses through all the .desktop
files but says "lacks mimetype key" for each one: 

[root at localhost ~]# update-desktop-database -v 
Search path is now:
[/usr/local/share/applications, /usr/share/applications] 
File '/usr/local/share/applications/marlin.desktop' lacks MimeType key 
File '/usr/local/share/applications/gnome-mud.desktop' lacks MimeType
key 
File '/usr/share/applications/xfce-panel-settings.desktop' lacks
MimeType key 
File '/usr/share/applications/redhat-evolution.desktop' lacks MimeType
key 
File '/usr/share/applications/gnome-default-applications.desktop' lacks
MimeType key 
File '/usr/share/applications/gnome-terminal.desktop' lacks MimeType
key 
File '/usr/share/applications/gnome-session-properties.desktop' lacks

File '/usr/share/applications/gnome-devhelp.desktop' lacks MimeType key 
File '/usr/share/applications/gnome-dasher.desktop' lacks MimeType key 
File '/usr/share/applications/gnome-bug-buddy.desktop' lacks MimeType
key 

etc. 

anyone else seeing this? i'm not sure where to put a bugzilla entry.
