Usually it's pointless to try to specify an output argument with a
mapset qualifier (most modules will/should just exit with an error).
Anyway, what version of GRASS do you have? I fixed a bug about 1.5 months
ago that could lead to such a problem if the output name was a GRASS
fully qualified name (<name>@<mapset>). I presume this doesn't happen if
you don't use a fully qualified output name?
