Freeze when trying to view details screen in the "System" section

Binary package hint: software-center

Ubuntu Software Center 2.1.18.1, Ubuntu Maverick

I encountered this while testing a fix for bug 636004, and found that it occurs in 2.1.18.1 itself.

To reproduce:

1. Navigate to "Get Software" > "System" > "A Better CD Encoder" (abcde), and click the "More Info" button.

On my machine, Software Center freezes at this point and does not return. It happens quite often, though not every time.

Note that this only happens when the full list is 28K or so items is displayed. If I use a search string to narrow the list (typing, say, "abcd") and click "More Info" from there, it works fine every time. Note also that this is the only package that I could find that causes this problem. Hrm.

When I hit <ctl>c in the terminal I get the following:

Traceback (most recent call last):
  File "/usr/share/software-center/softwarecenter/view/appdetailsview_gtk.py", line 1059, in _on_allocate
