true, but i did find the root cause. ;)

somewhere in bouncing between OS X, linux and (seldom) windows, this
umlaut became decomposed. or was entered decomposed. (I can't remember
which computer i wrote _those_ lines of code on). Didn't really matter
whether I was viewing the file on OS X (with preview) or evince on
linux -- the umlaut was shifted and two squares, rather than 2 round
dots over the U. sooo:

maybe. the ligature problem occurs with the 64-bit version of pango
shipped with lilypond, but doesn't with the 32-bit version. maybe the
32-bit version doesn't have problems with decomposed diacriticals, but
as i fixed my input file before installing the 32-bti version of
lilypond, i can't really test that immediately. and testing it ranks
rather low on my priority list right now -- currently it works. what i
will test, as soon as i get round to it, is if i can get lilypond from
the distribution .tgz to use my installed pango libraries rather than
the bundled ones -- at the moment, i can only generate scores with
ligatures on my linux box, which isn't my main working machine...

sb
