Grace notes and slurs

[Davide Romanini]

Still annoying problems...

I have this code:

\grace b8( )a4( ... )b

So it should make a grace note b, with a starting slur, then an a4 note 
with the previously opened slur closed and opening a new slur. Lilypond, 
instead, makes a single slur starting from the grace note that ends on the 
final b!! The strange thing is that on the sammartini.ly example, there is 
a similar thing, that fails to compile as well... :-(
It seems to be a nasty bug on my Lilypond 1.4.2jcn2...
There's a 1.5.x version for windows?
