Comment 1 for bug 191280

same here, clicking on a spot near the middle of the box brings up a menu with 'i386' on it (probably a drop down box for architectures). Clicking around the lower right hand corner of the window, makes the window disappear and the following error message appear:

/usr/lib/python2.5/site-packages/apt/__init__.py:18: FutureWarning: apt API not stable yet
