Comment 21 for bug 147045

I had this problem of gnome-appearance-properties process not ending even after pressing Close. I don't have a ~/.gtkrc* folder. After reading through this bug report, I remembered that I had installed some gtk2 themes and used gtk-theme-switch(2) to preview and switch the themes. I had a couple of gtk2 themes in ~/.themes folder. I removed the gtk-theme-switch package. Then I did a 'apt-get autoremove' and 'apt-get autoclean' and deleted the the 2 themes in ~/.themes. Now g-a-p quits as soon as I click Close.

Maybe this helps. I did this just a few minutes ago. I've also been having a problem with the display completely hanging if the screensaver is left running a little while. I don't know if that problem is related to this bug. I'll have to test that.
