[Gdal-dev] Error appears in 1.4.3 which wasn't in 1.4.2

[Seth Price]

I have another bug for you guys. This seems to have appeared in 1.4.3.  
It seems to be having a problem with my '-dstnodata "0 0 20"' option.  
With the current version, GDAL errors out and produces a 4KB GeoTIFF.  
With v1.4.2, no error is produced and the GeoTIFF is as expected.

Am I doing everything right here?

v1.4.2:
$ ./gdalwarp -dstnodata "0 0 20" -of GTiff -ts 256 256 -t_srs  
'+proj=merc +a=6378137.0 +b=6378137.0 +wktext +units=m' -te
