I can also confirm that the edgy released package broke my system, and the rc13 package fixes it.
There are 1-2 small new features between rc11 and rc13, but I don't think it is important to strip out the added features and only backport the bug fixes, since rc11 regressed for the vast majority of those using this package; I don't think we need to worry about rc13 regressing from an already broken version.
