I see the same issue with DejaVu Sans and DejaVu Sans Bold as well.

With LilyPond 2.17.0, I ran a few short tests, analyzing the PS output
and corresponding PDF output after every run.  The strange thing is
that the PS output always looks correct!  For example, here is the
glyph string from a failure case, which is output as "azaz" in the
PDF:

5.6906 -33.3571 moveto /DejaVuSans 3.86523438 output-scale div selectfont
1.1609 0.0000 0.0000 /z
1.5023 0.0000 0.0000 /Z
1.1609 0.0000 0.0000 /z
1.5023 0.0000 0.0000 /Z
4 print_glyphs

Also, if I run `gs test.ps` on this file, the output looks correct, so
Ghostscript (9.06) must be failing to correctly convert this PS file
to PDF.
