Then perhaps you should read line 8 of this script?

Maybe I'm blind but everything appears to be quoted correctly to me. The lines
below generate a string, gs_call in which all paths are certainly quoted.
gs_call = '%s -dNOPAUSE -dBATCH -dSAFER -sDEVICE=pnmraw ' \
'-sOutputFile="%s%%d.ppm" ' \
'-dGraphicsAlphaBit=%d -dTextAlphaBits=%d ' \
'-r%f "%s"' \
% (gs, latex_file_re.sub("", latex_file), \
alpha, alpha, resolution, ps_file)
If you were to add
print gs_call
immediately afterwards, you'd see the resulting string output to the console.
Something like:
gswin32c.exe -dNOPAUSE -dBATCH -dSAFER -sDEVICE=pnmraw -sOutputFile="C:
\Program Files\LyX\~\blabla%d.ppm" -dGraphicsAlphaBit=XXX -dTextAlphaBits=XXX
rYYY "C:\Program Files\LyX\~\blabla.ps"
for some integer XXX and YYY.
Maybe the '\' directory separators need to be escaped?
