Does the error occur without the patch? Does your patch solve it? If yes, what is it you are asking us? If not, what's the new problem?
The correct way to submit patches is the bug tracker, so if you think your patch is good, add test cases to the test suite, update the documentation if anything needs documenting, and submit your code+docs+tests patch to RT.
