Sorry but I don't get it. Why are you talking about a table? The "v.patch -a"
has nothing to do with it.

Anyway, isn't that strange that the output of a valid command (according to
manual) is corrupted, so that GRASS can use it and QGIS can't, until v.build
is run on it?

I do realize that the command looks strange, but I thought this issue might be
and indicator of something wrong with v.patch.
