georeferencer plug-in produce wrong results

[epifanio]

he georeferencer results give me a broken or not-well georeferenced image. I tried more than one georef-mode, helmert tsp, linear ... both gived me a wrong results (the pdf report font/layout size, is ok).

I tried to georeference a an already georeferenced image (gtiff). seems the problem is in "srcY" that has a negative sign, see : ​http://img811.imageshack.us/f/didefault20100612a14573.png/ ???

i tried on revision : r13719

I use it regularly, and found no problem. More investigation needed to check if it's replicable.
