Looks like we are doing the same debugging in parallel :-)
I decided that this was caused by some wired rounding error between 
CGFloat and float, where the float value was bigger than the 
corresponding CGFloat value. So I changed the floats in the typesetter 
code to CGFloat and now it works for me. I will write a ChangeLog entry 
and commit.
