Skype does not detect a webcam, even though Cheese is working correctly.
After looking into this, I found that i386 gstreamer doesn't have a v4l2src element installed. Would this be a dependency issue, a gstreamer or a packaging bug?
$ sudo apt-get install gstreamer-tools
$ gst-launch v4l2src ! xvimagesink
(... shows webcam image on screen ... press Ctrl-C ...)
$ gst-inspect | grep v4l

$ sudo apt-get install gstreamer-tools:i386
$ gst-launch v4l2src ! xvimagesink

First thing was that gstreamer1.0-plugins-good wasn't installed, which provides the video4linux2 gstreamer elements. Skype doesn't seem to depend on this.
After installing this, it still doesn't work, though gstreamer does:
$ sudo apt-get install gstreamer1.0-plugins-good:i386
$ sudo apt-get install gstreamer1.0-tools:i386
$ gst-launch-1.0 v4l2src ! xvimagesink
