Comment 1 for bug 1891027

I can confirm the error and it seems to be for the reason you guessed. We are including the name in the regex itself.

>>> import re
>>> re.compile("-[TBE134N-2.61]-")
Traceback (most recent call last):

re.error: bad character range N-2 at position 8

I think we will need to re-work this part of the code to make it safer in situations like this.
