Are you seeing a normal typeset in the Print View?

this says that the MIDI file didn't load (possibly because LilyPond
failed to generate it)

This says that Denemo could read the SVG that LilyPond should have
generated.

These are also due to the SVG being undreadable

and this is the GTK finding the SVG erroneous.

Is this with LilyPond 2.18.2 or with unstable? To find out why it failed
to create MIDI and SVG in detail you can use the LilyPond view (on
GNU/Linux, and possible Mac) or exporting the LilyPond (it needs to be
the LilyPond as generated by the typesetting for the Playback View) and
then running LilyPond on that (with a -Ipath-to-denemo's
actions/lilypond directory).
