Hi everybody.
For some unknown reason, the icon in the applications tab changed. It is now the corresponding applications icon in the TANGO iconset. The theme I'm using is oxygen, the style is also oxygen. The icons in the other tabs belong to oxygen, but the applications icon is different. No matter what theme I use, this particular icon won't change to match the theme. I also created a new user and checked the menu; the annoying icon is there too, which means the problem is system wide.
Does anybody know where KDE's kickoff menu looks for the icon? I could go there and change it, but I don't know where it is.
