Subject: [PATCH] Bug 541743  - Closing two tabs from yelp.com in rapid
 succession crashes Camino [@ nsCOMPtr_base::assign_from_qi(nsQueryInterface,
 nsID const&) | nsDocShell::FirePageHideNotification(int) ] [@
 nsDocShell::FirePageHideNotification(int) ], so hold a strong ref to the
 docshell. Patch by Christopher Henderson <trendyhendy2000@gmail.com>, r=bz,
