  Sorry, somehow I read your first line as "Has anyone noticed ...
output troubles ... ?", so my "yes" was an answer to that misread
question.  Trying to catch up with hundreds of e-mails in one evening ...

  Anyway, the problem is really strange, because by analyzing the
particular font with which I ran into the problem, I really got the
impression that the units per em "should be" 1000, since most glyphs
have advance widths around 600 or 700, which seems a clear hint that the
intended number of units per em is more like 1000 than 2000.  And, as
reported on the thread on Typophile, the problems seem to go away when I
edit the font in FontForge and change the units per em number from 2048
to 1000, without modifying anything else.
