Do you mean the MW installer would create a corrupted DB? ;-)

Of course. And once again, it is the same with the old upgraded wiki and with
new install.

That's not impossible, but any other MySQL-based application works fine (MW
1.15, other CMS, etc.). As I showed before, this really seems to be related to
the MW 1.17 files.

I can try a fresh install of the last MW 1.16.x, if it could help?

I have backups, I can test the sites (or a fresh install) on another machine.

> * dump/restore the database to ensure there's no internal consistency errors

Should I really do that on a fresh install? The database is the one created by
the installer, verbatim.
