Yes, setting the projection to Google Mercator (EPSG:900913) is very
important (you can use the "Enable 'on the fly' CRS transformation"
box to reproject your data, assuming the projection for your data is
set correctly). This error looks like a QT problem, though. Do you
have qt-python installed?<br>

I find it quite temperamental (v1.6), but generally only if I have
data already loaded that is in a different projection. Starting a
project using google mercator seems to be fine. Although often
after adding the data I have to drag the map about before it
refreshes and then it zooms out to the whole world.<br>

Had used it quite happily with previous versions of qgis and
indeed these versions.<br>
