See #11567.
Furthermore, it renames pythonPackages.dbus to pythonPackages.dbus-
python as that's the name upstream uses.
There is a small rebuild but I couldn't figure out the actual cause.
* pitivi: 0.95 -> 0.96 (fixes startup error)
The upgrade of gtk3 to v3.20 broke pitivi, causing it to segfault after
the user closes the Welcome dialog. This release fixes that.
New dependencies: gst-transcoder and dbus.
(pitivi imports dbus if it finds the GNOME_DESKTOP_SESSION_ID
environment variable. Without dbus there will be some ugly errors for
GNOME desktop users.)
* pitivi: use wrapGAppsHook instead of makeWrapper
Allows us to remove preFixup.
* pitivi: move meta section to the end
Like most Nix package files are written.
