gvfsd-sftp crashed with SIGABRT in g_assertion_message()

I think this might have been caused by Deja-Dup, which is currently running a network backup. I think it's still running, but I don't know for sure. It's uploading now. The bug looks like an error over an ssh session, which is the method Deja-Dup is storing the backup.
