There is no longer a /usr/share/mission-control folder, so we can't place the profile file until the new location is found. Perhaps someone knows what happened to mission-control?
To help others figure it out, the attachments listed earlier are part of this bug report, comments 3 and 4:

Karmic uses mission-control 5. It would see that getting facebook chat working in Karmic should require installing the pidgin-facebookchat package and then deleting /usr/share/telepathy/managers/haze.manager. Unfortunately, I still can't get it to connect.
