image displayed in the bubble when actualizing

Hi there!
I'm at the ubuntu bugskuad and I've found this bug:
https://bugs.launchpad.net/ubuntu/+source/gwibber/+bug/527446
The reporter suggest that when gwibber actualize and it shows the notify bubble. Why not to use the avatar of the tweet's owner? Currently it shows the gwibber's icon.
It seems like a nice idea ;)
