Ah, I forgot to share how I reproduce this bug:
While a video is playing in firefox:
Once a while I disconnect and connect the earphone headset via
gnome-control-center.
I connect my android cellphone to the earphone headset while it is still
connected to computer, "forcing" a disconnection.
All that while still keeping gnome-control-center bluetooth page open/scanning.
After a few cycles, of connect+disconnect the earphone headset shows as
"connected" in gnome-control-center, but no audio sink is available.
At this point, closing the lid or switching bluetooth off (via
gnome-control-center toggle) I get this message in dmesg:
