Rhythmbox F23 goes wacky

[SternData]

Before I bugzilla it, is anyone else seeing this?

 From time to time, since upgrading to F23, Rhythmbox gets very confused 
about where it is on a track, shows a VERY LARGE falue from the current 
position, and stops playing.

When I close it with the X, the window goes away, but rhythmbox itself 
doesn't.  I have to kill it from a terminal session.
