[MonoDevelop] Can't create display binding (0.10)

[Marcin Wielgus]

It happens when i try to create new files (not all but some, like gtk  
window, gnome program, empty file - about 50% of file types). I'm using  
monodevelop 0.10 under fedora 4. mono i have was downloaded from  
http://www.go-mono.com/download/fedora-4-i386/ yesterday (i downloaded the  
zip files manualy). Please help, or ignore if it was mentioned here before  
(i'm new here).

here are the details:

Exception occurred: Can't create display binding for mime type:  
application/octet-stream
