Opening preferences menu crashes CTE

I've confirmed this. The following stack trace came from the Mac OS X console. The error only occurs when running a stand-alone version of CTE (ergo, not out of Eclipse). The error is almost exactly like the error we had when trying to open a preferences file that doesn't exist yet. The two that we have included in the bundles are workRoom.preferences and CTE.preferences.

I've confirmed this. The following stack trace came from the Mac OS X console:
