side menu (List of Categories) displays links but no names

[Vanamali]

I use a CQ40 laptop with Ubuntu 12.10 installed.
Software-center version: 5.4.1.3

The attached image shows a screenshot the software center(USC). You may notice that the list of categories on the left side is missing (One can find an empty box!). Even though it looks empty, when I hover the mouse pointer above it, it indicates the presence of hyperlinks. Those hyperlinks work, but one doesn't know which category it links to until you click the link. I tried changing the font, font size, it didn't work. When started through terminal, I got the following messages:

Please help.

I ran "software-center --debug". The results can be found in the attachement.

Thank you for taking the time to report this problem.
What theme are you using? It's clearly not the default Ambiance nor Radiance. I suppose it's a theming bug, e.g the background is the same color as the text on the links, that would explain why the cursor changes when hovering over the link.

[Vanamali (vanamalishastry)]

The current GTK theme is 'Radiance'; Cursor theme is 'DMZ White'; Icon theme is 'Human' (These results were obtained through the terminal as the tweak tools have both crashed). Further, the problem is not with the color of the text. The text size have shrunk so much that, the links appear to be a continuum i.e, no break between the consecutive links.

I'm also affected, I use the theme Adwaita on GNOME 3.8 Ubuntu 13.04
