problem using "open with" in gnome 2.8.0

[Services - Nigel Kukard <services lando co za>]

i'm having trouble using "open with" in gnome 2.8.0...

1. if i click "properties" on a .pdf file
2. click "open with"
3. click "+ add"
4. choose  "gpdf"
5. click "add"

it still says  "No applications selected"

i downloaded all the gnome 2.8.0 sources, platform and desktop and built 
it myself.... maybe i left something out?


Thanks
Nigel
