Can you give us a little more information? Has it always been like that? What's your Xcode version? Have you repaired permissions from Disk Utility, anything else? – slhck Sep 18 '12 at 19:21
No, I first encountered this error after upgrading to Xcode 4. My Xcode version? Xcode 4, dunno the subversion right now as I'm booted into Windows. Permissions could be the issue, dunno. – mcandre Sep 18 '12 at 21:54
