The bug has a crash signature, thus the bug will be considered confirmed.

Note that not all crashes are related to necko, but there are some crashes happened in nsHttpTransaction::Init.
Maybe it's worth to add a shutdown check in nsHttpTransaction::Init to avoid initialize a transaction during shutdown.

We should add the shutdown check in the nsHttpTransaction::Init and see if this intermittent goes away.
