[pygtk] hungry TreeStore...

[Laszlo Pandy]

I have no idea what it is but I was having the a similar problem on my
Ubuntu 8.10. Funny thing is that it wasn't consistent, so whenever i
got terrible performance I restarted the app and this fixed it
temporarily. Not sure if this is related because I didn't do any
performance testing or profiling. I will test again later.
