It looks like some sort of memory-handling error; perhaps you are
unreffing something you shouldn't be. (Note that
soup_session_queue_message() steals your reference on the SoupMessage,
so you do not need to unref it afterward. And also, if you want to stop
a message you have queued before it has finished, you can't just unref
it, you have to call soup_session_cancel_message()). But it's impossible
to say without seeing the code.
