Is it time to move the lists off sourceforge yet?
When my Bluetooth mouse disconnects and reconnects, I sometimes see
this. I can't easily reproduce just by turning it off.

Reverting commits f5ffd4620aba9e55656483ae1ef5c79ba81f5403 and
e1aaadd4d8162a2c33e41dd5a72234ea4d3b014f (my first suspects) didn't fix
the oops. It just makes it looks like this instead:
