Unreproducible here in a xenial chroot w/ same versions of dpkg and libglib2.0-0. The format of the triggers file looks correct. Yan, is this problem reproducible if you run 'sudo dpkg --configure -a && sudo apt -f install && sudo apt install libglib2.0-0' in a terminal? Otherwise, my guess is that this a rogue bitflip error rather than a bug in libglib2.0-0.
