Still missing important debug information I'm afraid.

'seems the trick is to compile with "-ggdb"

It's trying to build the Time delay effect which needs the
"frei0r-filter- delay0r" plugin (which lives in the
gst-plugins-bad package). Cheese should probably do better at avoiding crashing when an effect 
isn't available.

Could you please re-test with cheese 3.12.x, and file a bug if
the problem persists?

Thanks

Hmm - assuming we're referring to /usr/local/lib/gstreamer-
1.0/libgstfrei0r.so, it is present and correct...

Are you sure that your GStreamer installation knows to go get the
plugin there?

Some progress being made at last

I don't see it written anywhere, but the gstreamer frei0r plugin requires
frei0r-plugins in order to work.

Are you filing bugs about this, or are we just debugging your hand-made
distribution?

There's a test call cheese-test-monitor in the cheese sources which you can
use to debug your problem. The device monitor code uses udev to
enumerate devices. Attach the output of "udevadm info --export-db" so we
can see if the camera is detected properly.

cheese-test-monitor doesn't do anything (cheese-test-camera seg faults).

Udev output attached

Thanks
John
