Hi all,
I'm testing QGIS 0.10 on Debian and I see a bug about manage of the
custom CRS.

In the past version I had a custom projection like this:

+proj=tmerc +lat_0=0 +lon_0=9 +k=0.9996 +x_0=1500000 +y_0=0 +ellps=intl
+towgs84=-104.1,-49.1,-9.9,0.971,-2.917,0.714,-11.68 +units=m +no_defs

and I used this like default CRS for the geographical data without
projection file and to reproject on the fly data from an another
proiection system with good result.

In the test vers 1.0 I have this problem:
1) if I set this custom projection like default projection the data is
associated with WGS84 lat long projection
2) if I use this custom projection to make reprojection on the fly, QGIS
automatically use CRS 3003 (EPSG code) instead of my custom projection
with relative errors of projection.

Anyone have similar bugs or know why it happens?

Thank you very much

Leonardo
