Extent information should be updated once themes have been removed

[mika.heiskanen@…]

Occasionally one may accidentally mix shapes in different coordinate systems in the same view. Once the wrong shape has been removed, the zoom to full extent button will still remember the extent as if the wrong shape was still there. If the actual shape was in regular latlon units and the wrong one in projected units measuring say in the millions, pressing the button will result in an empty view. Finding the latlon data again requires zooming down several times around the origo.

The fix should be to update the (obviously cached) extent information whenever data is being removed from the view.

This has been fixed in version 0.8.0 of qgis. Version 0.7 is over a year old, so we suggest that you upgrade your version of qgis.
