Re-opened since this is blocked by bug 266899
Thanks for noticing this and sorry for the mess. Indeed, the g_signal_handler_find() call is looking for any registered handler, regardless of the userdata used to register it. There may be legitimate third party handlers still registered for that m_stream or that m_pad. I think it would be reasonable to just remove the assert. I'm going to prepare a new patch without the assert.
