All records are rasterized, except those with value of the selected field = 0. This seems inappropriate

if you mean the training manual exercise data then I cannot see any "basins" layer. Better attach the data is giving you problems.

I tested on both QGIS master and 2.8.1 on both Linux and Windows and in all cases, with the provided vector, there are no issues and the polygon with attribute = 0 are correctly rasterized to pixels with value = 0.

If you use the tool and choose "byte" as type for output you must pay attention to the value used for nodata, as -9999 cannot fit in such type and so it is automatically changed to 0.

Got it, thanks. Perhaps a better default could be chosen for nulls?

maybe is better to change the default type to int16?
