Since Alexandre is now planning to do a 1.0.1 release, I created a 1.0.1 target in bugzilla, and have targeted a very few high priority and/or fixed-but-not-in-time bugs to it. Many of the bugs currently targeted for 1.2 are not good candidates for targeting to 1.0.1 because the bug is not yet well understood and/or a fix is not yet known.
I think the rule of thumb for further nominations should be something like "if it's already fixed in trunk, and the fix is easy to backport to 1.0, then it should be nominated for 1.0.1."
