App crashes when disabling gapless playback
I tried running the app via Gnome Builder, and upon crash it logs the following:
(com.github.neithern.g4music:2): GLib-GObject-WARNING **: 22:03:09.360: g_object_get_is_valid_property: object class 'GstPlayBin' has no property named 'about-to-finish'
Both on 1.6.1 and on master.
