On QGIS master, clicking on an attribute table's row header to select a given feature is broken. Instead of selecting one feature, it'll select all features from the first row all the way to the row you've clicked on. The issue is visible with datasets opened through the ogr as well as spatialite providers (possibly more providers affected, I just haven't tested others)

1. Create a new project
2. Add an existing shapefile (or spatialite) vector layer, insure the dataset has a large-ish number of features
3. Open the attribute table
4. Click on the row header of the fourth row
5. While the feature associated to the fourth row should be selected, you'll notice row 1, 2, 3, and 4 have been selected
