That's some help, thanks!

Any location:

v.random map1 n=1
v.random map2 n=1
v.patch -a in=map1 out=map2 --o

Try opening map2 in QGIS - no layers available. However, you can display and
query it fine in GRASS.

v.info map2 doesn't report anything suspicious. However, running v.build map2
or opening it with v.digit, validates it for QGIS.

I wonder whether this is an issue with QGIS or v.patch.
