I have a weird QGIS-Problem that only occurs in Ubuntu 12.04, but not in Windows 7. I've also tried this on different Ubuntu-Computers.
When I try to transform a layer with WGS84 to a different projection type (example Austrian Gauss Kruger) the result is shifted exactly 300m to the East to where it should be. This happens with both "on the fly transformation" and when I save the Layer in a different CRS!
When I save a WGS84-Layer in Gauss Kruger and I open both the new and the old layer in Ubuntu, they overlap perfectly (with on the fly-enabled). When I switch to Win7 and open both layers (the original and the one I created in Ubuntu) I can even see the 300m gap!
And ideas? Could this be a bug? Thanks!
(I am using the same EPSGs in Windows and in Ubuntu - I can also see/not see the problem, when I open the same project in Ubuntu/Windows.)
