"Install" button sensitive for dependencies already queued for installation

[Schwarzburg]

Ubuntu Software Center 4.1.23.2, Ubuntu 11.10 beta 1

1. Search for python-django.
2. Select python-django-websocket (which Depends on python-django), and choose "Install".
3. While it is installing, select python-django, and choose "Install".

What happens:
* The "Install" button is sensitive.
* Once python-django-websocket finishes installing, the "Install" button changes to "Remove".

What should happen:
* The "Install" button is insensitive.

<https://wiki.ubuntu.com/SoftwareCenter#software-list-view>: "The “Install” button should be insensitive if the item is currently installing or queued for installation."

I forgot to say why this happens a lot to me:

I search for a term: e.g. 'django', then I go through the list of packages and click on install if I think that I will need them.
Chances are high, that there is an interdependency between many packages that contain 'django'.

The error message no longer seems to appear, but the "Install" button is still sensitive when it shouldn't be. I'll update the report.
