cheese shows a black preview, taking pictures works though... here is the output of cheese -v: plugin-scanner:2894): GStreamer-WARNING **: Failed to load plugin '/usr/lib/gstreamer-0.10/libgstplaybin.so': /usr/lib/gstreamer-0.10/libgstplaybin.so: undefined symbol: gst_stream_volume_get_type (plugin-scanner:2894): GStreamer-WARNING **: Failed to load plugin '/usr/lib/gstreamer-0.10/libgstvolume.so': /usr/lib/gstreamer-0.10/libgstvolume.so: undefined symbol: gst_stream_volume_get_type Cheese 2.28.0 Probing devices with HAL...

looks like a broken gstreamer installation?
i have trouble with cheese... it won't let me see "preview" while i sign (yes, i am deaf though). it was total black than i played the movie. i can see myself but not as GREAT.. yes, i changed the numbers but still not working.. i was expected that cheese should be clear but no... that made me so frustrates. please solve this problem for me.thanks!
Felix, I can reproduce this one as well. As soon as you enable one of the effects, preview will appear, and any pictures you took will appear too. Looks like a dupe of bug 596899 *** This bug has been marked as a duplicate of bug 596899 ***
