[Qgis-developer] Openlayers plugin issue

Hi John

I tested your vector data both as shapefile and from postgis and the borders 
lined up nicely with Google Maps on my QGIS build.

The custom SRS should have the following Proj4 config:
+proj=merc +lon_0=0 +lat_ts=0 +x_0=0 +y_0=0 +a=6378137 +b=6378137 +units=m 
+no_defs

Usage note: The data is only aligned for integer values on the zoom level 
slider.

Could you send me a screenshot of your QGIS map?

The map composer is not supported at the moment. There are still a lot of open 
questions regarding fixed zoom levels combined with resolution scaling and user 
defined viewports.
