Thanks Marcus-

I guess we are prejudiced against filenames with spaces so there were no ch=
eck for this in the system calls to GS and GDAL.
Fixed in r10252 (GMT4) and r13441 (GMT5).

  You can use an exact custom papersize to impose your own boundingbox, or =
use ps2raster -A if you want a tight one.
