Is it actually broken? As far as I can tell, importing the module still works.

May be I do something wrong... I try to update python-urwid:

**********************

pkgname=python-urwid
pkgver=0.9.8.3
pkgrel=1
pkgdesc="Urwid is a curses-based user interface library."
license=('GPL')
arch=('i686' 'x86_64')
depends=('python')
makedepends=('mercurial' 'pyrex')
url="http://excess.org/urwid/"
options=(force)
source=(http://excess.org/urwid/urwid-$pkgver.tar.gz)
md5sums=('52a7e6d15e12a12b1ae62c0c901b2c20')

build() {
cd $startdir/src/urwid-$pkgver
python setup.py install --prefix=/usr --root=$startdir/pkg
}

**********************

/usr/lib/python2.5/site-packages/Pyrex/Compiler/Errors.py:17: DeprecationWarning: BaseException.message has been deprecated as of Python 2.6

Or it seems urwid problem...

Yes, my bad, please close it
