I am attempting to import an SVN dump file into Rational Team Concert using the RTC process described here:

I get an error on a particular commit that fails the import and results in a stack dump like this:

I've tried changing the encoding on the import in many ways. I've also tried importing up to 1 changeset before the failing one and then trying to import the failing one with multiple encodings, nothing works. If I strip out this changeset and skip it the import will fail a few hundred commits later. Looking at the commit that fails, nothing special is done, only editing a dozen lines in a few source code files in the baseline. Any thoughts?
