System installed in English, but later played with locale and/or GUI regional settings. After a while, I reverted everything to English, but software-center still used French for the short descriptions of packages (and English for the full descriptions).
I deleted "/var/cache/software-center/" and "/var/cache/apt-xapian-index/", which made software-center crash.
Running
sudo apt-get --reinstall install software-center
fixed it, and everything is in the correct language.
