you need to add a test for plone 4.1 sites upgraded to 4.2/4.3

plone.app.collections (which your package's GenericSetup depends upon) is not installed by default in these circumstances, as a result installing flowplayer (HEAD master) blows up with (Collection, '') exception

Start by locating the package's GenericSetup configuration and existing tests, then review how plone.app.collections is handled when upgrading Plone 4.1 sites to 4.2/4.3. Add a regression test covering installation of flowplayer in that scenario and confirm the Collection exception no longer occurs.
