The "classifiy as spam" and "classifiy as not spam" icons disappeared from the tools bar. If I add them back, they appear for a second, when I switch to kmail, but then disappear. Runnig the anti-spam wizard does not help either.

Addition: in kmail (runnig separatly) the icons are there in form of question mark icons. In Kontact if they are missing.

Addition 2: now in a separate kmail the icons are gone too. I think there is something wrong with those icons and toolbar

Addition 3: there 2 icons for "classifiy as spam" and "classifiy as not spam", one with the proper icon and one with the question mark icon

Any ideas?
