Public bug reported:

When I convert from PDF to HTMLZ, then modify/save anyway the index.html file inside HTMLZ, next convertion from HTMLZ to EPUB fails.
If I let untouched the HTMLZ file (even making an unzip + zip action) the conversion makes no error.
I tried to edit index.html file with editors like kate and vim.

I'dont really know if apt-get update calibre or not, but I always do
conversions like that until 1 month ago.

The error detail is:
