TYPO3 Core

In one step of the Upgrade Wizard "Deprecated RTE properties in Page TSconfig" are detected.

Problem:
After changing all listed properties the Step in the Upgrade Wizard still fails.

Cause:
For one conversion the test does not work because the name of the property does not change as in other cases:
replace "showTagFreeClasses" by "buttons.blockstyle.showTagFreeClasses and buttons.textstyle.showTagFreeClasses"

Part of where conditions which always applies:
SELECT uid, TSconfig FROM pages WHERE (TSConfig LIKE BINARY "%RTE.%showTagFreeClasses%" AND TSConfig NOT LIKE BINARY "%RTE.%showTagFreeClassess%")

Possible solution:
(TSConfig LIKE BINARY "%RTE.%showTagFreeClasses%" AND TSConfig NOT LIKE BINARY "%RTE.%blockstyle.%showTagFreeClasses%")
