[Taihsiang Ho (tai271828)]

precise uses Python 3.2.3 and it has no contextlib.suppress. (this explains why trusty could not reproduce this issue. Trusty uses python 3.4.3)

[Taihsiang Ho (tai271828)]

Refer to Makefile.am, Cheese-3.0.typelib was compiled based on Gst-0.10 (on trusty it is based on Gst-1.0). This makes Cheese.Camera is not supported.
