Two weeks ago locally installed the trunk with MySQL.
Today I deleted my LocalSettings.php and some other files that were created by the installer and/or by me.

I reverted everything to the state as it was and then 'svn up'ed to the latest revision (r75747) and I went through the installer again giving it the name and access to my existing (albeit pretty much empty) mw database.

I got the message that it's possible to upgrade, and to do so click Continue (I found it weird though, there's no "clean install" option, only continue or back).
After clicking continue I get this on http://localhost/svn/wiki/config/index.php?page=Upgrade
Upgrade existing installation
Warning: you requested the binary schema, but the existing database has the mysql4 schema.
This upgrade script can't convert it, so it will remain mysql4.

Version: 1.17.x
Severity: normal
