looks like just basic gtk2 stuff
i have seen similar reports periodically from various gtk apps and i think it has to do with the theme you are using. seems like i remember some qt type theme ?
i remember you said you were using KDE -- if your gtk apps are using your KDE theme
that's not normal so it's a cool hack your os builders have done.
i guess if it's not slowing stuff down it's ok to ignore it
