Description

Using the 'save as' dialog to overwrite a shape file writes a new empty shape file, losing all the previous data in the shape file.
Steps to reproduce:
Create a new vector layer from the 'Layer: new' dialog, select 'New shape file layer'
Edit this layer, (I just set it editable, added some random points, saved changes when prompted when I turned off edit mode)
Select 'Save as' from the 'Layer' menu, leave options as defaults, Format 'ESRI Shapefile'; navigate to original file name, select in file browser.
Select 'Replace' in dialog.
Delete layer from QGIS.
Go to 'Add layer', select the shape file you just saved
Import it.
All the data has disappeared, including the attribute table.

I'm pretty sure this didn't happen in 1.8.
Also, if you skip the 'Save as' step, and delete the layer then re-import it, the data is fine.
It's the step of using 'Save as' and overwriting it that delete all the data.

Running on MacOS 10.7.5
