I've just re-upgraded libpng back to the "broken" version and tested against the previously breaking file, and now all appears fine... yeah, looks like file corruption. I also saw something similar at one point while trying to install a new xulrunner-1.9.2 which appears to have fixed itself as well, so I guess something's sorted itself out. Thanks for the help, please close the bug.
