[pygtk] Refresh data on TreeView

[Julián Alarcón]

Hi guys, I don't know if this is the right place to bother you with
this support ask.

I'm making a little app that takes data from PostgreSQL and show it on
a TreeView. But, I need to update the data every 5 minutes, but I
don't know how to make this. I tried some while loops but the window
didn't appear.

This is the code: http://paste.ubuntu.com/397321/

And this is a little screenshot: http://i42.tinypic.com/14yaazs.jpg

Thanks!
