beaming bug

[Federico Bruni]

I disabled emails from lilypond-bug so I hope this has not been reported
already.
The attached snippet worked fine with 2.13.58, it broke since 2.13.60 (I
never tried 2.13.59).

Here's the error message in the console:

programming error: No viable beam quanting found.  Using unquanted y
value.
continuing, cross fingers
