Bug#894439: pitivi: fails to start with message "gtk not found on the system"

[Antonio Ospite]

Package: pitivi
Version: 0.99-2+b1
Severity: important

Dear Maintainer,

since GStreamer 1.14 pitivi may fail to start when freshly installed
because of a missing dependency:

  $ sudo apt-get install pitivi
  $ LANG=C pitivi 
  ERROR - The following hard dependencies are unmet:
  ==================================================
  - gtk not found on the system
  Missing soft dependency:
  - GSound not found on the system
      -> enables sound notifications when rendering is complete


This is because the GStreamer gtk stuff has moved to a separate package,
installing gstreamer1.0-gtk3 fixes the issue:

  $ sudo apt-get install gstreamer1.0-gtk3

Having an explicit dependency would be great.

BTW I've seen other users bitten by this split in GStreamer plugins.

I do like the split but maybe things can be improved a little:
  - Recommend or a least suggest the split packages from the one they
    are split from.
  - Use a more familiar naming? Someone proposed something like
    "gstreamer1.0-plugins-good-gtk3" but I am not sure if you meant to
    hide the -good/-bad/-ugly origin on purpose here.

As always, thanks.

Ciao,
   Antonio
