Comix crashes when Edit Archive function is used on some CBR archives

Binary package hint: comix

For some reason that I can't seem to pin down, Comix crashes when going File | Edit Archive with certain CBR archives. In each case, I am able to manually unrar the CBR (by right-clicking on it and selecting Extract Here) and recompress it to a CBZ without error.

When this occurs, Comix is totally frozen and must be killed.
