totem-mozplugin requires the exact version of gecko-libs = 1.9, which is replaced by gecko-libs 1.9.0.1 in the latest xulrunner (xulrunner-1.9.0.1-1.fc9). This stops "yum update" working if totem-mozplugin is installed. Either totem-mozplugin needs a rebuild or the dependency needs to be relaxed. This is similar to bug #455803
totem-2.23.2-5.fc9 has been submitted as an update for Fedora 9
totem-2.23.2-5.fc9 has been pushed to the Fedora 9 stable repository. If problems still persist, please make note of it in this bug report.
What is the chance of getting this fixed in FC8? I have tried for several months since the release of a stable FC9 to load it on my system and have not had any luck, there is always a problem with reading the packages.
