Comment (by mmetz):

Replying to [ticket:2239 sbl]:
> Converting areas from vector to raster (v.to.rast) with the -d flag
(dense lines) results in an empty raster map.

Converting areas and densifying lines is mutually exclusive. Line
densification is now (trunk r67918) disabled if areas are converted.

>
> This is probably/likely because boundaries are not lines in a topolgical
sense.

You can now convert boundaries with

{{{
v.to.rast type=boundary layer=-1 use=val
}}}

>
> In any case, it would be helpful to catch this behavior at least using a
warning/error message and by adding information to the manual.

Done in trunk r67918.
