TYPO3 Core

i will add a check for reports module (there are already 3 integrated)

Patch set 1 of change Ifad1a7e81fbec4a22707a7a12090234dbb7b9496 has been pushed to the review server.
It is available at http://review.typo3.org/6991

Although this error can also occur in 4.5, I would not add this check there, as soap is not a required PHP extension in this version (was added starting with 4.6).

Extension key handling is an edge-case, I guess many developers use 4.5 to do this. Instead, adding a new requirement (at least that's how it looks like) in a patch-level release would IMHO cause more confusion. Feel free to comment, if you have a different opinion!
