Just updated to Xcode 5 and this is the first error its throwing on the logger for all my apps. Can\'t seem to understand why this is happening.

I had this problem with Xcode 5 in ML 10.8.5
I re-installed Mountain Lion (in a Parallels' VM), then update ML to 10.8.5.
Then installrd Xcode 5, and it's worked fine.
I think that the error is caused by a third SW installed in ML.
