LilyPond has encountered a problem and needs to close

[Zoltan Selyem]

%%
%% On Windows XP:
%% If there is no \layout block but a \midi block and
%% there is no \header block I get a window saying that
%% "LilyPond has encountered a problem and needs to close".
%% (The MIDI file is created properly.)
%%
%% I get no error if there is a \header block, but
%% I don't need the pdf...
%%

\version "2.11.65"
% \header{ title = "x" }
\score{
  \new Staff { g' g' g' g' }
  \midi{}
}
