Interestingly enough, with LilyPond 2.10 I only get one fatal error.  It trips
a false positive in the "rendering failed and brackets were turned on"
warning code. The brackets are fine.  The problem is you can't put an ottava
and a hairpin at exactly the same place, apparently.

We should save a copy of the old Ravel and attach it to a bug report
documenting this LilyPond export quirk, but this kind of situation comes up
more often than you'd think, and it might not be practical to put in detour
code to try to cope with this confluence of Rosegarden elements in one spot.

The practical field solution to a problem like this is to move the hairpin.  I
deleted it, then moved it to start one note later and end one note sooner,
and it cured this for me.  (I achieved this with Thorn, although it would
have been easier with the modifier keys hooked up.  Shift click to do a note
by note selection doesn't work yet.)

Now that other bit you got about \sustainDown I can't duplicate here with
2.10, so it must be a 2.12 thing.  I don't have a copy of 2.12 handy to test
this out.  With 2.10, simply tweaking the hairpin starting at bar 90 makes
the file work.

Anyway, I'd file both of these as separate bug reports on SourceForge, as they
are long-term problems.  The hairpin rendering failure happens for me just
the same in Classic, and I imagine the other one would too, if I had 2.12
around to reproduce it.
