Description
How to reproduce:
- Download this 0.7 MB shapefile: http://geocommons.com/overlays/5603.zip
- Open the shapefile and set up EPSG 3416 for On-the-fly (other systems also work)- Zoom out as long as you can
- QGIS crashes at a certain level (obviously depending on the coordinate system; might be quite early)The funny thing is, it doesn't happen in Windows.
That might help as well:

This is probably a Qt problem. The Qt in OSGeo4W is patched with the attached patch. See also http://lists.osgeo.org/pipermail/qgis-developer/2010-August/010669.html

So the patch for osgeo4w means that under windows does not crash?
Has the patch been submitted to fix qt upstream?
