'DBGLLDBLauncher' not found for required key 'workerClass'

Hi everyone,

Below is the top of a crash report that I got today for a project that had been working correctly until today. It occurs as soon as I hit the "Run" button in the project window.
To the best of my knowledge, I've not made any changes in this project since I last ran it successfully several days ago.

Further info:  System 10.7.5,  Xcode version 4.4 (4F250)

Any suggestions as to what might have gotten messed up and how I might fix it would be greatly appreciated.

Boyd
