As you can see here, some icons are working...
It seems only KStandardAction are affected
You can change that. Go to "Configure Toolbars...", select the action, then
"Edit Text...". There is a checkbox that allows you to toggle visibility.
We'll improve the user interface in 4.7 for this, as currently it is too hidden.
