Xcode raises exception when refactoring


When I run a refactor on my code in xcode, all the files are correctly refactored except one, and when I click to check the changes made in that file, the following 'Internal Error Occurs':

Uncaught Exception:
Invalid parameter not satisfying: fileName

Stack Backtrace:
The stack backtrace has been logged to the console.

Here is what it spat out in the console:

If you would like to take a look at the project I'm working on, here is a link to download my xcodeproject: Tea Timer.zip

To recreate my problem, open Timer.h, attempt to refactor timeField to minuteField, use the preview function of refactor and then select Timer.m, to look at the changes supposedly made within. It will then raise this error without editing the file.

Works great on the Xcode 3.2.1(64 bit) running on the Mac OS X 10.6.3, so that it seems to me that you are using the older version of the Xcode or the beta one. For the future, it would be better to report such errors to the apple bug reporter, so that guys from Apple would take care of the issue, cause those are the only with the source code :)
