Subject: [PATCH] pk-transaction: Check that Finished signal is emitted at most
 once
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While I haven’t seen it being emitted more than once, the transaction
code is quite complex, and it would make things more robust to add a
check to verify this.
