The openlayers plugin will only work with projections that Google et.al
is using - that means EPSG:900913 or EPSG:3857 (which essentially is the
same projection). So you are restricted to these two projections for
your project. If you want to add (vector) layers with a different
projection to the map, you have to enable "on the fly" CRS coordinate
transformation for the project.
This works for me (TM) :
* Create a new empty project in QGIS.
* Add an "openlayer" based layer. A map of the globe will be
displayed. The project CRS will switch to EPSG:3857. "On the fly"
CRS transformation will be enabled.
* Zoom in to the area, you are interested in.
* Add a normal vector layer (in my case, a tab file). This will be
displayed reprojected to EPSG:3857
Windows 7-64 bit, QGIS 1.7.4 rev. 411aff6, openlayers plugin 0.92.
If you still have problems, you could try to install QGIS ver. 1.8.0.
The two versions of QGIS "lives" in different directories and can co-exist.
NB ! When I change the project projection to EPSG:25832 (ETRS89/UTM32N)
the plugin _doesn't_ crash. But the layers are misplaced and have a
"wrong" north

Hello,
I have experienced consistent issues with the latest OpenLayers plugin
with QGIS 1.7.4. The only way I can get the plugin to work is if I
open a new QGIS project, set my project CRS to Google Mercator (EPSG:
900913) and then add an OpenLayers layer such as OpenStreetMap or
Google. However, if I then add another layer, for example a shapefile
in EPSG: 4326, QGIS crashes. If I set my project to anything other
than Google Mercator, QGIS crashes as soon as I try to add an
OpenLayers plugin layer to the map canvas. This makes the plugin
unusable. I have experienced this on multiple machines. Any suggestions?
I'm running:
- Windows 7 64 bit
- QGIS 1.7.4 built against code revision 8058b22
- OpenLayers plugin v 0.92
- GDAL/OGR 1.9
- QWT Version: 5.2.1
- compiled against Qt 4.7.1
Thanks,
Kurt Menke
