It would appear to be at least correlated to
<URL:https://code.google.com/p/lilypond/issues/detail?id=3483>,
version 2.17.24 (it is easy to do
git revert 6e8698dcb9a9b9a98d8b1a644c84fcb737f99bdc
in order to experiment with this).

It is not clear to me what the exact relation is, however.  It may be
that the problem just surfaces with different sizes.  The change results
in pango_font_description_set_size receiving numbers that are rounded
rather than truncated, so pango_font_description_set_size will receive a
number that may be larger by up to 0.5 than the exact number.  I would
think that this does not affect the overall problem but will likely
change the cases where those are most prevalent.

I might be mistaken here, however.  That would warrant experimentation.
