My apologies, here are the testing files attached.
Any chance you could open a bug in bugzilla, and attach these files there?
At first glance, it looks like those files have some certain text patterns
near the start which is causing them to be mis-detected as not-text. We
might need to try altering those patterns a bit
Otherwise, if you know a file really is a text file, you could either call
the text parser directly, or try setting the content type to strengthen
the hint
