I had kde-gtk-config installed but it was crashing when I would go to it in Application Appearance. So I did sudo apt-get remove --purge kde-gtk-config and readded the kdegoodies ppa and reinstalled it. Now it does not show up in application appearance. How can I fix this?

Have you tried running "kbuildsycoca4"?

I got this:

xplorer4x4@xplorer4x4-MS-7673:~$ kbuildsycoca4
kbuildsycoca4 running...
kbuildsycoca4(24794) KConfigGroup::readXdgListEntry: List entry MimeType in "/usr/NX/share/applnk/x-nxclient/nxclient.desktop" is not compliant with XDG standard (missing trailing semicolon).

But GTK Config shows up now, but it just freezes up that window when I click on it..

lol I just tried to access the menu again, and for some reason it worked now..

Good to hear it is fixed.
In regard to the output of "kbuildsycoca4" that can be safely ignored.

Well half way fixed. I was messing around with the icon settings and it froze up on me. Now it just freezes when I try to click on the GTK Config icon.This has been by far the single most unstable app I have used.

The GTK Configuration utility is 3rd party, and is loaded by System Settings when you try to use it. Other actions may initiate it being loaded - which are likely causing the freeze.

Do the freezes go away when you uninstall it?

Yes they go away if i remove --purge it and then the app functions the next time I load it only to freeze up on me sooner or latter..

Can you determine if particular modules cause it to hang? It should not hang under normal circumstances, and if it does it highlights either a problem with your system (possibly dbus) or a defect/regression in KDE.

No I can not pinpoint it to a particular module for sure. It was the icons this time but I think it may have been the styles that caused it previously. I purged it again, but now I cant access the settings page for it at all.

I checked the dbus.log and it had this in it:
Unknown username "whoopsie" in message bus configuration file
Unknown username "whoopsie" in message bus configuration file

Is there another particular log I can check?

This is extremely odd. Please use your distributions support methods to check if this is indeed intended behaviour or if it is the result of a damaged configuration file.

Could you specify a config file?

The configuration file is likely one of the files under /etc/dbus-1/ (either session or system).
