rests at changing staffs

[Henning Hraban Ramm]

Hi,

I typeset a piano piece for a friend, and she thinks my rests are wrong (the upper staff should have the r2 and the lower the r8).

But this happens if I change the staff in LilyPond, like in:

es g d' c r \change Staff = "left" g, a b \change Staff = "right" |

Usually LilyPond is right. ;)

What do you think?

Best, Hraban
