A couple of problems have recently cropped up in the latest development of Totem, and we've tried our hardest to solve them.
One problem was that some files contained the exception to allow the linking of proprietary GStreamer plugins, but the addition of that exception wasn't agreed upon by the copyright holders.
This was the case of the plugins system (fixed), and the sidebar widget (fixed as well). The nautilus properties page was a draw. If we make it GPL with an exception, it wouldn't work anyway, as nautilus is GPL, and the properties page is linked directly in nautilus. The plan is to write a D-Bus helper, which would allow us to avoid hangs when checking the properties of some file.
Those relicencing was what kept me from making a release for 2.19.x, but it's sorted now
. Many thanks to the copyright holders that allowed this to happen.
