triplet problem in multi-staff score 2.7 and 2.6 versions

[Jay Hamilton, Sound and Silence]

I'm having a problem that I can't see to fix.
Here's the file.
The problem is pdf output at measure 36 third staff.  The triplet or 
something has made the staff spacing huge.  Since it's the only place 
that this is happening and there is nothing that I can see in the file 
that makes it this way.  I'm stumped.

This was a problem in 2.6x too but I thought maybe it was me.
Jay

oh yeah running this on xp
