Comment(by snorfalorpagus):

 Still having this issue with r46963.

 I've noticed that if I turn on labels (display=shape,attr), select an
 attribute (attrcolumn=whatever) and change the label background/border
 colours, the boxes for the labels appear in a size proportional to the
 text, but the text does not display. When I leave the d.vect dialogue
 (pressing OK) and go back into it, the attrcolumn is removed from the
 command at the bottom and in the input box. If GRASS then tries to redraw
 the labels (pressing Apply), the console outputs the following:


 {{{

 I guess this is due to the automatic removal of the attrcolumn.

 I'm not sure where else to go with this.
