TYPO3 Core

I know of tons of installations where some deinstalled extension in typo3conf/ext/ gets renamed to "tt_news.old" or "news.bak" etc. This was no problem before.

With the new package management feature, this now throws an exception on first hit:

InvalidPackageKeyException('"' . $packageKey . '" is not a valid package key.', 1217959510)

Solution:

The loop that scans for packages should skip those who's key is not invalid, in order to avoid an exception later down the road.
