 Binary package hint: pidgin

 pidgin 2.6 added audio/video chat support. that's incredibly awesome!

 however i did not get video chat working if only one party has a camera.

 Scenario:
 user A has a microphone and a camera
 user B has just a microphone

 they use jabber and send text messages ever since, and now audio/video
 chat is available and they want to use it.

 case 1: user B starts an audio call to user A. everything works as
 expected! awesome.
 case 2: user A starts an audio call to user B. everything works as
 expected! awesome.

 case 3: user B starts an video call to user A.
 actual behavior: following output to debug log and no call at all:
 ------------------
 (15:09:01) mediamanager: gst pipeline error: Cannot identify device
 '/dev/video0'.
 (15:09:01) mediamanager: Debug details: v4l2_calls.c(482): gst_v4l2_open

 system error: No such file or directory
 ------------------
 expected behavior: voice call + video from A to B

 case 4: user A starts an video call to user B.
 actual behavior: following output to debug log and no call at all:
 ------------------
 (15:11:40) g_log: purple_media_get_account: assertion
 `PURPLE_IS_MEDIA(media)' failed
 (15:11:40) g_log: purple_find_buddy: assertion `account != NULL' failed

 (15:11:51) g_log: purple_media_stream_info: assertion

 ------------------
 expected behavior: see above

 sometime the following is displayed in the chat window:
 ------------------
 media: Error with your webcam.
