Yes, you're right.

Yes, those look like bugs. I guess so few people have been playing with
fixed widgets no-one noticed or complained until now.

pack() was never quite finished as an addition to the standard widget
methods. Text has one that can be used to calculate ideal sizes for
wrapped text, and BigText has one for defining its fixed size, but
that's about it.
The plan was to use it for shrinking all sorts of flow and box widgets
and to return sizes for fixed widgets, but that got delayed after I
started to plan some big changes to the way containers work (and factor
out a whole bunch of common code). Those big changes haven't happened yet.
If you are willing to write those missing pack() methods that would be a
great help.

I've had so much ticket spam that I redirected the login URL to
"/urwid/login-removethis" The trick is to remove the "-removethis" part
and then logging in should work.
