Seems caused by merging dual-view branch.

Steps to reproduce:

1. open any vector layer
2. open attribute table
3. select on row, then try to select another row or select several features
4. QGIS crashes with "Segmentation fault"

Sorry, I can't reproduce this here.

Can somebody else confirm?

Alex, what dataprovider are you using?

I tried postgres (with and without "select at id") and shapefile.

Tested with shapefiles (sample dataset attached) and with postgresql/postgis (connection settings http://gis-lab.info/qa/geosample.html#PostGIS) with same result. QGIS crashes with "Segmentation fault". Here is last few strings from console output

Can't get anything useful from gdb.
Maybe local issue. Anyone else can confirm?

Confirmed with the attached shapefile. Will look into this.

The attribute table was a bit overactive in feature selection. It called setSelectedFeatures twice subsequently. Apparently QGIS didn't like this.
