Will test again and see when I get back into the office on Wednesday. I
patched this because I'm pretty sure I saw the duplicate certificate
error (adding blobs via the D-Bus control interface with a patch I've
yet to post). However, looking at the code I can see your point. I'll
have to go back and dig a bit more to see if this is still a problem
without the patch in 0.5.9 and if so get a callstack for you.
