Note also bug 332454.
This seems fixed for me in 1.8.1 (Mozilla/5.0 (Windows; U; Windows NT 5.0; en-GB; rv:1.8.1b1) Gecko/20060710 Firefox/2.0b1). The test cases in bug 330478 and bug 332454 also work. Probably related to "the handling of 1-bit images is horked (bits are packed backwards). I'll fix." comment in bug 329598.
