I can not change the icon associated with some file type ( .txt text-plain as example).
Instead of the txt icon it show the python file (.py) icon.
If I try to change the icon in the control panel ( http://imgur.com/PgXfZ4X ) nothing happen after selecting the new icon. This happen only for certain association.
Someone can help me fixing this please.
EDIT: Forgot to say. KDE4 on archlinux.
