Hi, i found out that the line /usr/bin/defoma-app update fontconfig isn't enought to do the job. It keeps the cache up-to-date, but reconfiguring fontconfig does something else, i can't figure out. It seems as if the whole fontsystem itself has a leak. I'll talk to the fontconfig-devs, maybe they got a solution of it. (it seems that a cronjob is needed to keep the cache clean and up-to-date) Thanks for your help anyway! -Matthias
