ha! I guess I found the error.
Please try again *without* specifying the mapset (@lonsdale). If it is
not in the path, use g.mapsets (-s for GUI) to add it.
Runs, right?

The bug is here:
    sprintf(buf, "SELECT Interp,ID FROM %s_edge_Interpolation",
in_opt->answer);
    db_append_string(&sql, buf);

in_opt->answer contains (in your case) the @mapset part which causes
the DBMI engine to crash. So that should be easy to fix in the module.

@devs: how to strip off the mapset part of a name? Don't remember...
