Description
trying to calculate area and perimeter from a simple shapefile with CRS WGS84UTM32 following these steps:
1) set up the CRS of the project to WGS84UTM32 (on the fly transformation is checked)
2) load the shapefile
3) click on it with the identifier tool (identify features) I obtain:
- area: 19.321 km2
- perimeter: 0.221 m (!!!!)
then I modify the general CRS settings for new project (settings --> options) to WGS84UTM32 and, after reloading qgis, I did steps 1, 2 again and I obtained:
3bis) in the identify tool:
- area: 19.321 km2
- perimeter: 20.392 km
The second couple of results seems better! It seems that part of the identify tool use the CRS of the project (area) and part the general settings (perimeter). I added a sample test.
I sign it with high priority because is a very annoying bug when someone try to present qgis to new users ...

Similar issues (but with the area in the field calculator) have been already fixed in qgis master, and in fact I can't replicate this issue.
Please give a try with qgis master and report back if it does not work for you.
Cheers!
