Affects: gnome-python-extras (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
gnome-python-extras should run make check during package build, so any
unexcepted errors using the bindings will be easier to catch.

The wnck bindings in breezy were broken, it would have been caught if
make check was used.
