Created attachment 476962 [details] Crash log I've experienced a couple of crashes since installing STP 229. The crashes did not occur in STP 228. I think this happens after closing a tab. Attached are crash logs.

It hits this: RELEASE_ASSERT(iterator != m_sessionToPageIDsMap.end());

So far it looks like it's a pre-existing issue that just happened to occur twice. But please let us know if this continues to be a problem.
