I'm running QGIS 2.2 on Ubuntu 14.04. Trying to project data gives me a hard time right now.
The last time I did that was in 2.0 and I basically changed the projection by saving the data as a new file with a certain layer CRS and opening it in another QGIS project. That doesn't work right now, even when on-the-fly transformation is disabled in the project properties.
I've been trying project some vector data with WGS 84 geographical coordinates on WGS 84 UTM 32 N (Germany) but see no results from changes I make in the project or the layer properties.
