No anti-aliased fonts after KDE 4.2 upgrade (in most applications)

Description of problem:
After my latest yum update, most applications do not display any anti aliased
fonts. The fonts are hard to look at and very difficult to work with; see attached screenshot. Some applications like konsole work fine. Most of the others including Firefox don't. Surprisingly, even 'System Settings', which I thought was Qt based doesn't display anti-aliased fonts.
Version-Release number of selected component (if applicable):
Can reproduce always
Steps to Reproduce:
1. Start firefox
2. Start 'System Settings'
See attached screenshot
Really cool fonts that I've been used to in KDE 4.1
That's strange, the app on the screenshot is Firefox which isn't even a KDE app.
Are you sure this was caused by the KDE 4.2 update and not some other update? What graphics hardware/driver are you using?
Also, mind including the relevant parts of /var/log/yum.log that include details about pkg updates between when things were working and not?
I have the nVidia Quadro FX 570M with nVidia's latest driver installed (177.82). Everything was working fine before the KDE 4.2 update; I have no bulletproof guarantee that KDE 4.2 is responsible though. BTW, even KDE apps display the bad fonts now - konsole and 'System Settings' as well -- it's strange that I can't reproduce it always with konsole and 'System Settings', but always with firefox as far as I've used kde 4.2.
/var/log/yum.log is attached.

Hmmm, the thing is, this seems to work for everybody else... You have a lot of third-party stuff on your system: there's the nvidia driver and then there's tons of IBM packages, some of which got updated at the same time as KDE according to your log. It is hard to pinpoint the source of the trouble, but I suspect either a bug in the nvidia driver or some third-party app screwing up your fontconfig settings.
Have you tried logging into GNOME? If non-KDE apps in GNOME also look broken, then I don't see how KDE is to blame. KDE almost certainly doesn't mess up global fontconfig settings, you wouldn't be the only one to complain if it did. ;-)
I logged into GNOME. The fonts are bad there too, in fact worse, with all the GNOME desktop menus displaying fonts with no anti-aliasing.
My nVidia driver has remained unchanged through the yum update and everything was fine earlier. What packages should I reinstall to reset fontconfig settings? I reinstalled fontconfig, but it didn't help. Thanks.
There was .fonts.conf in my home dir. I deleted it and the problem is now gone. There is no longer .fonts.conf in my home dir; don't know which application created it or messed it up.
I think my .fonts.conf was generated by 'System Settings' from Appearance -> Fonts -> .... I remember changing some of my font sizes and a custom .fonts.conf was generated; it created the problem.
User configuration issue, closing.
