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?
