empathy crashed with SIGSEGV in g_type_check_instance_cast()

Binary package hint: empathy

I presume apport gives you all the relevant info.
Basically, empathy crashed on Natty without warning. I wasn't on the computer when it happened, I was grabbing a drink while my computer was dist-upgrading and came back to see that empathy had crashed, so I'm not sure how to reproduce it. In case it's relevant, I only use Empathy for MSN.
