[Qgis-developer] slow raster loading

Hi Tim,

just tested your last commit and I still see

Warning: Object::connect: No such signal
QgsGdalProvider::statusChanged( QString )
in /home/gio/qgis-Quantum-GIS-4b4820e/src/core/raster/qgsrasterlayer.cpp:2446

I copied a geotiff in a folder with no write permissions and it took a
lot of time to open the raster, much more than it used to take when
opening the same image the first time in a folder with write
permissions.

Then I compiled QGIS with your last commit and now it seems it is not
collecting stats/creating the aux.xml file anymore.

cheers
