GCompris is a large software which has numerous dependencies. We ask packagers to be very careful and follow this minimal and manual test process.
e.g: in the gcompris source directory run: totem boards/voices/fr/misc/ok.ogg
It you see the following error in the console, then you need to fix your gstsreamer:
(totem:12015): GStreamer-CRITICAL **: gst_event_new_new_segment_full: assertion `start <= stop' failed
The administration module rely on python and pysqlite.
TEST: Run GCompris in full screen and check the desktop bars are under our window.
