Those warnings look like a bug in cheese or ekiga.

Does this command show something?

  gst-launch-0.10 v4l2src ! ffmpegcolorspace ! videoscale ! ximagesink sync=false

?

FEHLER: Leitung konnte nicht konstruiert werden: Kein Element »v4l2src«.

That would explain the above failures then I guess.

This is essentially a packaging issue, take it up with your distro please.

You need to install gst-plugins-good (or whatever package your distro put v4l2src in).

Feel free to file separate bugs against cheese and/or ekiga. They should handle this case properly and show you a proper error dialog.
