tkldev-changelog not working with typo3

[JedMeister]

When I try to update the Typo3 changelog via tkldev-changelog I get this error/stacktrace:

Traceback (most recent call last):
  File "/usr/bin/tkldev-changelog-extractor", line 127, in <module>
    primary = process_changelog(args.changelog)
              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/bin/tkldev-changelog-extractor", line 83, in process_changelog
    changes[current_v][-1] += line
    ~~~~~~~~~~~~~~~~~~^^^^
IndexError: list index out of range

I assume that it's something funky in the changelog that it doesn't like, but I'm not sure and not going to bother with it now...
