I'm testing make valid on a sample of real data. It effectively cleans up all the topology errors, as found by the Topology Checker plugin, but geometry errors as found by the Vector --> Geometry Tools --> Check geometry validity tool are left untouched.

I'd appreciate an explanation on this difference; probably we should add it to the manual, and warn the user about it.

One probable explanation is that the two tools were coded in different ways (and as far as I understand in different languages) by different programmers, so at some level there is no match in what is considered an error and what is not.
