 I'm clipping an srtm90 raster using a rectangular window and the
 result is wrong:
 1. Wrong window
 2. The result has an additional layer with constant 255 value

 I've put the input raster, input vector and output raster here:
 http://dl.dropbox.com/u/3180464/srtm_37_04.zip
 http://dl.dropbox.com/u/3180464/FlxPyrAOI1.zip
 http://dl.dropbox.com/u/3180464/srtm3704FP2.zip

 Please give it a look before I actually fill a bug report.

 Surprisingly, the srtm90 tile to the W gets clipped right with the
 same vector (except that
 the constant 255 band is also present).
