opensuse 12.3 and kde 4.11

I love kate, but I have just a small issue with it. When a launch kate the toolbar is as I have set it. When I click on it, icons change place. All of them are still visible, but in different places. This happens for 4 or 5 clicks; then everything keeps its place (the last one, not the original one).
This has been happening to me for long: several versions of opensuse and of kde.

Is there anybody experiencing the same? Is there any solution?

Thanks!
