It also doesn't appear in the messaging menu either. Install unity-webapps-facebookapps didn't help, don't know how those two packages are related if at all.

Yes , I see that the .desktop file is missing.
As a workaround you can try this application
http://www.omgubuntu.co.uk/2012/07/fogger-can-turn-facebook-into-an-integrated-desktop-app-on-ubuntu

It might help you to turn the facebook into integrated app..

but this is just a workaround , the main problem remains and it would be good and useful if you report a bug.

Do you know how to report a bug ?
If No , then read here
