Luckily, we never actually have null there, afaik.
Summary: nsTableFrame::PushChildren will pass null to [@ nsFrameList::RemoveFrame] which doesn't want it → nsTableFrame::PushChildren imagines it can pass null to [@ nsFrameList::RemoveFrame] violating its preconditions
ok, i read the code and agree this shouldn't happen. my current mailbox also has no indication of a crash for this codepath.
