I figure it must be my installation. 

I've tried versions 2.11.62-1.mingw and 2.12.2-1.mingw (on an XP machine), but
it's rejecting my sustain pedals, even using template D.2.4 (Piano centered
dynamics) and the pedal-bracket.ly snippet
(http://www.lilypond.org/doc/v2.10/Documentation/user/lilypond/source/input/regression/lily-56f3d0fd9e.ly).

For completeness, this minimal snippet:

\version "2.10.0"
\paper{ ragged-right=##t }
{      a1 \sustainDown  b \sustainUp       }

produces this log:
