Created attachment 65475 [details] font kcm Using master, For an unknown reason, the font kcm displays incorrect fonts for a few entries. See the attached screenshot. The unreadable entries come from a font called "!Y2KBUG" However, this is not the font I chose (and not the one used). From kdeglobals: XftAntialias=true XftHintStyle=hintfull XftSubPixel=rgb desktopFont=Droid Sans [unknown],9,-1,5,50,0,0,0,0,0 fixed=Droid Sans Mono [unknown],9,-1,5,50,0,0,0,0,0 font=Droid Sans,9,-1,5,50,0,0,0,0,0 menuFont=Droid Sans [unknown],9,-1,5,50,0,0,0,0,0 shadeSortColumn=true smallestReadableFont=Droid Sans [unknown],9,-1,5,50,0,0,0,0,0 taskbarFont=mikachan-PB,10,-1,5,50,0,0,0,0,0 toolBarFont=Droid Sans,8,-1,5,50,0,0,0,0,0 I tried changing the values back to Droid but when reopening the font kcm, the issue is back. (screenshot attached)
Note that your config file says "Droid Sans" and "Droid Sans [unknown]", which might be the problem. What Qt do you use? Those entries are saved by Qt.
That's Qt 4.7.4 and now that you mention it, in qtconfig/fonts, the !Y2KBUG is the first listed in the Font substitution drop down menu (the current substitution list is empty however)
note that "Droid Sans" and "Droid Sans [unknown]" are two different fonts. In the font selector, the first one is called "Droid Sans [misc]" hence the difference
I just retried: - Changing all the droid fonts back to Droid Sans [unknown] # grep Font ~/.kde/share/config/kdeglobals desktopFont=Droid Sans [unknown],9,-1,5,50,0,0,0,0,0 menuFont=Droid Sans [unknown],9,-1,5,50,0,0,0,0,0 smallestReadableFont=Droid Sans [unknown],9,-1,5,50,0,0,0,0,0 taskbarFont=mikachan-PB,10,-1,5,50,0,0,0,0,0 toolBarFont=Droid Sans [unknown],8,-1,5,50,0,0,0,0,0 activeFont=mikachan-PB,10,-1,5,50,0,0,0,0,0 and when re-running kcmshell4 fonts, they're all listed as !Y2KBUG again
The fonts kcm uses KFontRequester (more precisely, a simple subclass of KFontRequester) for choosing and listing fonts. Move it to kdelibs/kdeui. But I guess this can only be fixed by Qt.
