It seems you have to specify the llayer parameter too,  e.g.

d.erase;d.vect pts2 layer=2 display=shape,cat llayer=2

It is really confusing, I am not sure how to solve it. Do you think,
would be enough to print a given warning, e.g. "The layer number (2)
and layer number for labels (1) are not the same.".

Best, Martin

PS: I am really looking forward to the new bug tracker! Thanks Maciek
for working on it...
