Looking at the backtrace, the problem was that in StreamingClient::handleResponseReceived(), we'd lock the WebKitWebSrc, then notify on several properties. One of the other threads tried to access the WebKitWebSrc, and then we get a deadlock. I'm pretty sure we're not supposed to notify while holding locks, so I just freeze the notifications while we're locked.

I'm really not that familiar with GLib though, so I'm not sure if this is the preferred way, or if we should do something different, like queuing up the notifications in a Vector<const char*>. This seems to be what freeze/thaw is meant for though.
