[Qgis-developer] QGIS 2.6.0 georeferencer fails in windows

[Roy]

Dear list,

i'm georeferencing some rasters and the georeferencing process fails (in 
winodows osgeo4w 32bit) with
this message:

  failed to compute GCP transform: Transform is not solvable

the georeferencing process works in linux using the very same data 
(raster and GCP list)
is it only my system or should i open a bug report ?

thanks,

Roy.
