Created attachment 358789 [details] testcase Steps to reproduce: 1. Load the testcase 2. Quickly quit (Cmd+Q) Result: nsGenericElement and lots of other objects leak (as reported by trace-refcnt) Probably not a major user-facing leak, since it only happens if you quit at the right time, but gets in the way of leak testing.
No longer leaks on trunk. Probably fixed by the patch in bug 503989.
