Description
Reproject layer works ok with QGIS default CRS, but doesn't do any reprojection with custom CRS.
I'm with QGIS 2.0.1 from OSGeo4W, doing transformations with grid files.
Some custom CRS I've tested:
+proj=tmerc +k=1 +lon_0=1 +no_defs +x_0=200000 +ellps=intl +nadgrids=C:\\proj_lib/ptLX_e89.gsb +units=m +lat_0=39.66666666666666 +wktext +y_0=300000 +pm=lisbon +proj=tmerc +k=1 +lon_0=-8.131906111111112 +no_defs +x_0=200180.598 +ellps=intl +nadgrids=C:\\proj_lib/pt73_e89.gsb +units=m +lat_0=39.66666666666666 +wktext +y_0=299913.01

Hi Pedro,
is this a regression? What about on linux (it may use a different proj version)? Can you send me (if you can't attach them) sample data and grids?

Hi Giovanni,
On linux is the same.
I can't check if this is a regression, because on 1.8 I get another error when I try to change the CRS:
An error has occured while executing Python code:

I attach a sample shapefile. It's a selection of the portuguese caop, on EPSG:3763.
Thanks!

so this is a SEXTANTE/processing only issue? the same tool in the "vector" menu works as expected?

using your sample data, projections and grids the result in sextante/processing is a vector that has attributes but no geometries, correct? at least here it is what happens. The "save as..." option seems to work ok, do you confirm?

I'm wrong, the output has geometries but it is given the wgs84 crs so it does not shows by default... it is needed to manually change its crs.

because the produced prj file is empty

Yes Giovanni, Save as.. works fine.

because the produced prj file is empty
Here there are two problems:
a) Processing creates an empty .prj file when using custom CRS;
b) In addition to the blank .prj file, "Reproject layer" actually does not do any reprojection, the output geometry remain with same CRS of the input layer.
