It seems that systems will not break where there 
is a glissando across the bar line (in 2.18.2). 
The break that occurs after bar 4 is the last bar 
line that isn't spanned by a glissando: hence the 
cramped nature of the second system, as no 
further breaks are possible. In addition, your 
articulation "decrescendo molto" is too long to 
fit on the second system, even if there is (just) 
room for the music. If you shorten this or stack 
the words using \column, you will just see the 
final bar line, though displaced into the margin 
- or at least I do with my default settings. If 
you drop one of the glissandi, you can see three sensibly spaced systems.

I trust this helps.
