Hi Emilien, I had a look at this package : http://mentors.debian.net/package/subdownloader Changing the source format in an NMU is usually not wanted, and the patch is very small, so you could simply add the change to gui/main.py and keep the old source format. On the other hand, I doubt that Marco Rodrigues is still maintaining this package, so maybe this shouldn't be an NMU. Regards, Bart Martens
