Crash on crossfade transition when mix Gst 1.16 and GES 1.14
When trying to watch a crossfade transition (added automatically by overlapping two clips) in in the viewer, I expect it to play normally, but instead, Pitivi crashes about two seconds before reaching the transition. When I try moving the playhead onto the transition, it shows me the transition settings, but crashes right after that. Both methods are reproducible for me.
When running Pitivi from terminal, it produces the following message on crash:
/usr/lib/pitivi/python/pitivi/project.py:1442: Warning: g_object_set_is_valid_property: object class 'GstCompositorPad' has no property named 'crossfade-ratio' self.ges_timeline = self.extract()
