[Telepathy] Unidirectional video chat with Empathy

[Pavel Johnson]

I was able to download Empathy 2.29.90 from Rawhide to test unidirectional
video.

Uni-directional video is not working on 2.29.90 either and based on some
tests here are a few observations:
* If a user has a webcam, the Empathy client on the other end shows the
webcam icon as a user attribute.  Even after removing the webcam the icon
seems to persist, which lead me to believe the other end thinks video chat
is still possible.
* I hence created a new user, and never connected a webcam.  However, it
still shows the user with a webcam icon.

In both cases when trying to establish the video chat (assuming video in one
direction would work), it fails and the Empathy client on the end where
there is no webcam throws a GUI error: "Can't establish video stream. There
was a failure in the call engine." Technical Details: Resource Unavailable.

Below is the log.  Please confirm if this is a bug and will appreciate if
you can let me know when the bug will be fixed - thanks much!
