Ticket #1325 (closed bug: fixed)
Multipoint layer problems - zoom to selection doesn't work; layer extent has wild values on editing

Vector layers of type Multipoint have the following problems:
1. Zoom to selection doesn't do anything.
2. When editing - adding or deleting points - the extent as shown in properties, Metadata goes to some wild values.
This causes zoom to layer extent to zoom to a very small scale, such that the scale bar on the map shows a distance on the order of 1e+200km
The points added are correctly positioned. Reloading the layer fixes the extents display.
some examples of the extents shown in Metadata (layer has a few points over about 1000m):
start: xMin,yMin 499999,5e+06 : xMax,yMax 501001,5.001e+06
add point: xMin,yMin 499999,-1.51934e-93 : Max,yMax2.95439e+202,5.001e+06
xMin,yMin 499999,5e+06 : xMax,yMax 1.09228e+209,1.2796e+156
delete point: xMin,yMin 4.94066e-324,-2 : xMax,yMax 4.94066e-324,2
I have tested with PostGIS and shapefiles.
Expected behaviors: Zoom to selection operates as it does for Points - a single point is displayed at a fairly large scale; multiple points should be displayed over most of the map view.
On add and delete points the extents should reflect the minimum/maximum of the locations of the layer.
