Andreas,

pudb.py looks exactly like something I was hoping to have time to write
myself.  Would you like me to distribute it with Urwid?

Your patches look fine.  I will include them in my repo (when it's back
online)

I have had some issues with scrolling long unselectable widgets that I
haven't fixed yet, this is likely what you're running into.  A simple
workaround is to break your text into multiple widgets, but the proper
thing to do is to add a test case to test_urwid.py with a really long
widget.  There are lots and lots of listbox test cases, but this looks
like one I missed.
