Git status brings strange message

[josipbernat]

I recently upgraded to OS X 10.10 Yosemite. When I type "git status" in Terminal to check status of my git repository I receive following message:
"objc[3015]: Class XCBuildConfiguration is implemented in both /Applications/Xcode.app/Contents/PlugIns/Xcode3Core.ideplugin/Contents/Frameworks/DevToolsCore.framework/Versions/A/DevToolsCore and /Users/giga/Library/Application Support/Developer/Shared/Xcode/Plug-ins/Peckham.xcplugin/Contents/Frameworks/MHImportBuster.framework/Versions/A/MHImportBuster. One of the two will be used. Which one is undefined."

Is problem maybe related with OS X 10.10 or maybe should I reinstall Peckham?

:) duplicate of #27. I wanted to fix this, just didn't have time.
