The current mission control (telepathy-mission-control-5.3.2-1.fc13) is not a stable release: "The 5.4.x branch is a new stable branch, starting from the last development release (5.3.2)."ยน Fedora 13 should ship a stable release, so mission control should be updated to 5.4.0 [1] http://lists.freedesktop.org/archives/telepathy/2010-April/004433.html
Building for rawhide now. Will push to F-13 once built.
