[R-sig-Geo] Intended usage of gIntersection ?

Dear list,

I'm trying to intersect two SpatialPolygonsDataFrames imported from shape  
files. (readOGR)
The idea is to get the new polygons + the merged attributes of both  
layers, but the outcome is a SpatialPolygon class without a data slot.

Is this the intended behaviour of gIntersection or is there something  
broken in my R-Installation, cause I googled now for 2 days to find a  
solution on that problem, but only found two hits on stackexchange where  
people had similar problems, and no working solution (at least for me),  
nor was I able to find any standard recipt how to join the attributes back  
to the new polygons.

So obviously only rare people seem to have the need to get also the data  
 from an intersection or do I miss some really basic R-capabilities not  
worth to write down in any documentation??

Hope someone can shed some light
