software-center crash at start since 13.10

[rmmonster]

Hi,
I have recently updated from Ubuntu 13.04 to 13.10. Today I wanted to install something with the software-center, but the application won't start.
I get to the point where the software-center Window is empty and then it crashes with the following stack trace:

Traceback (most recent call last):

I have attached a "full log" created with:
[...] $ software-center --debug &> software-center.debug.txt

Maybe this is a duplicate of https://bugs.launchpad.net/software-center/+bug/1199617

P.S.

$ software-center --version
software-center 13.10

The traceback is very different from the one in bug 1199617. However, it is similar to the one in bug 1019952.

I just did a fresh install of Ubuntu 13.10 except this time I'm using an older laptop that has to use the open source Galium drivers. Interestingly, Software Center seems to a whole lot more stable, it hasn't crashed once. So I think these issues are to do with the proprietary AMD drivers that come with Ubuntu 13.10. It could be that they are installing libs that are causing a conflict. Just a thought.

Status changed to 'Confirmed' because the bug affects multiple users.
