Take a look around https://bugs.freedesktop.org and see if you can find your issue there. If not, please file a new bug there. Either way, please post the resulting link here. Thanks!
Sorry took a while but after testing 1.4.5 I finally posted this bug upstream. https://bugs.freedesktop.org/show_bug.cgi?id=9261 But should we really mark this bug as resolved (as it is not yet)?
The resolution is Upstream, since we're waiting on them to fix it :)
