Unity4XC plugin showing failures with git command line

Hi, since installing the XCode 5 beta I get this output when I perform a git operation via the command line:

2014-06-19 09:56:32.615 xcodebuild[10910:d07] [MT] PluginLoading: Required plug-in compatibility UUID A2E4D43F-41F4-4FB9-BB94-7177011C9AED for plug-in at path '~/Library/Application Support/Developer/Shared/Xcode/Plug-ins/Unity4XC.xcplugin' not present in DVTPlugInCompatibilityUUIDs 2014-06-19 09:56:32.618 xcodebuild[10910:d07] Failed to load plugin at: /Users/link/Library/Application Support/Developer/Shared/Xcode/Plug-ins/Unity4XC.xcplugin, skipping. Reason for failure: *** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[0]

It doesn't seem fatal but I'd like to fix the problem. Anyone know what's going on here ?

Thanks.
