[SOLVED] Atahualpa 3.6.x - how to remove 'Categories'-links from right inner side-bar

Until recently, I was using Atuahualpa 3.5.3, without any problem.
Since a few days, my blog was having problems to load, that couldn't be solved by deactivating every plugin, and removing every javascript-widget.

I went back to 3.5.1, and the loading-problem disappeared, but then I noticed there have been several new releases since 3.5.3.
OK... trying out the latest one. I have desactivated it within minutes, since in the very narrow right inner sidebar were showing up 'categorie'-links, that don't belong there.
I don't know were the content comes from, since in the widget-section, there isn't anything in that inner sidebar (i use it just for having 'space' between my the center column and the right sidebar.)

I haven't noticed other issues yet, but this one was enough to deactivate the theme.
I also tried 3.6.1, but again, categories within that 80 px wide side-bar, and I want that to be empty...

Is there a solution?
