Current code in git master doesn't build:
pk-transaction.c: In function 'pk_transaction_finished_cb':
pk-transaction.c:1116:3: error: 'PK_BACKEND_SIGNAL_NONE' undeclared (first use in this function)
pk-transaction.c:1116:3: note: each undeclared identifier is reported only once for each function it appears in

plugins: Possibility to select connected backend functions
Via set_signals, backends can now select which signals
of the backend should stay connected to the transaction.
Sorry for that... For some reason it still compiled on my machine after removing the SIGNAL_NONE element.
This is fixed now.
