F16 Unable to change icon>K theme
After an upgrade from F15 to F16 I'm not able to change the icon theme, GTK+ theme and I have problems changing background too.
I have gnome-tweak installed but on Theme section the only thing working is Shell Theme, I can change the other ones but they have no effect.
The strange thing is that I have two users and all is working good on the second one so I guess is only some configuration on my first user that is causing the prroblem.
Question: can somebody point me on how to debug this problem or reset gnome configuration for that user?
