I've been looking at it. If you just let it choose what part of the
score to use for the thumbnail it picks a couple of bars at the start of
the first staff. This fails for the score concerned because there is a
second voice on the first staff. Selecting both voices and calling
Score->Set Thumbnail From Selection the thumbnailer then works ok.
The script that selects what to thumbnail by default should check for
voices ...

I've logged a bug report for this.
