Incremental updates from 6.0 to 6.0.1 are not working on OS X

I tried to update from 6.0 to 6.0.1 and first it downloads the incremental update. Verification is fine it seems but then I get the following error:

AUS:SVC Downloader:_verifyDownload called
AUS:SVC Downloader:_verifyDownload downloaded size == expected size.
AUS:SVC Downloader:_verifyDownload hashes match.

AUS:SVC UpdateManager:refreshUpdateStatus - Notifying observers that the update was staged. state: downloading, status: failed: 2

And the browser is falling back to downloading and applying the full update successfully.
