File association in Thunar keep changing to wine IE and Windows Media Player

view story

http://askubuntu.com – I have Xfce and in Thunar files association are changing randomly, to wine applications like jpeg and png to Internet Explorer and mp3 to Windows Media Player. I change it back to gpicview and Totem and after a while, when I click on the file it fire wine again (which take forever to load, and IE don't even work, so it load only to show some error) How can I make my file association, to permament, and not change to wine software.
