Bug#802306: packagekitd eating up RAM

[Matthias Klumpp]

Hi!
Can you check if this issue still appears with the latest PackageKit
in unstable (v1.1.0)?
I fixed a few minor memory leaks that I found, and there are also a
few other changes which might have an impact on this - although I am
still a bit in the dark on why this issue happens at all (still can't
reproduce it :-/).
Cheers,
    Matthias
