as per gavin, I am creating a duplicate bug 464984. That bug was blocking 1.0b2+, and we should consider that in setting the blocking-fennec flags. This would mean we have a regression.
This was fixed by bug 512277.
Sorry, I meant bug 511982 (which also fixed bug 512277).
woot! verified with 1.9.2 nightly 20090921 on my n810
