prism crashed with SIGSEGV in g_type_check_instance_cast()

Binary package hint: prism

I have created some webapps in my desktop using Mozilla Prism. One of that is Gmail. This Bug is related to this webapp and how prism handles plugins and installed Firefox addons.
Particularly it has to do with flash plugin and googletalk plugin. When I open Gmail Webapp it loads also googletalk. I suspect that this is when crash happens. But overall prism works great and I don't have any problem with the webapp that I create
