[Qgis-developer] Azimuth problem

[George Silva]

Hello everyone,

I was testing some features in Qgis and i have a shapefile (SAD_69, UTM 
22S) with a field AZIMUTH. Its a polyline (street centerlines) shapefile.

I tried to add labels and configure them using the "Align by field" 
property. Oddly QGIS is labelling all my labels ~45d off.

What kind of units does QGIS use to rotate the labels? Can it be configured?
