[GRASS-user] v.to.rast with empty vector-file

[Achim Kisseler]

Thanks for response, Markus!

I just did that a minute ago.

But I found out that I don't have to handle that exception in my case: I
do a r.patch further on, which works even if one raster-file is missing.
So there is no need of an null-map anymore.

Thanks again,
Achim
