hippo-canvas-0.3.0-2 (in updates-testing) is ABI incompatible with hippo-canvas-0.2.34
currently in F-9; In order to fix https://bugzilla.redhat.com/show_bug.cgi?id=456665
I need to rebuild mugshot against hippo-canvas-0.3.0-2.

[ mugshot is the only package that use the C API to hippo-canvas, though there are
other packages using the Python bindings, which are not affected, since they are
part of the hippo-canvas package ]
