Check the KVO-compliance of the IDEApplication class.

Above is the message in Xcode's problem report. Surprisingly, the .xcworkspace file works fine, but this isn't very helpful as I have integrated several API's in my project and hence can't run the xcworkspace. I haven't worked on this project in a few weeks but I don't remember running into this problem before. Thanks.
