[GRASS-user] r.li help

I did a little crude debugging yesterday (G_message) and found it  
failed for me in daemon.c, line 626 / nextArea()

     else {
	return next(g, m);
     }

But all this tells me is that at this point the mask name is missing,  
not where it was lost.

I didn't have more time to poke around more.

Note: bug report at http://trac.osgeo.org/grass/ticket/718

answer...
