[Qgis-developer] Georeferencer produces wrong (shifted) result

well, with my setup (ca. qgis 1.7), the output of the georeferencer  matches 
the output from ArcGIS pretty accurately (older revision of QGIS, though - 
haven't tested with head). 

See my result, georef output in green:

The qgis georeferencer output can be found here:

Please upload the output you got, both ArcGIS and georeferencer, so that
we can rule out problems on the visualization / on-the-fly reprojection
side of things. Also, at this point the exact version of your QGIS/GDAL
setup could be relevant.

There are some possible sources of error for the discrepancy, e.g. gdal, a
faulty entry in the qgis projection database, or user error (well, it happens
:-)).

cheers,

	Manuel
