While playing a bit with freegis country data r1 I found that qgis symbology manager
doesn't allow to use fields of type 'bigint' as classification fields for continuos color
or 'gradueted symbol'.

I haven't researched on whether the limitation also apply to other kind of types,
but I do see 'numeric' type is correctly handled.

This is 1.3.0 Mimas.

Sorry, another thing I haven't specified is that data access is trough postgres.
That's where 'bigint' and 'numeric' come from.

To recap: 'numeric' and 'integer' are known to work, 'bigint' is not working.

additional note, the type query returns 'int8' as looks to be expected by code in qgspostgresprovider.cpp constructor.

int8_classify.patch fixes the problem in both 'graduated' and 'continuos' thematizations.
reviews welcome.
