View Full Version : [gnome] All file associations are gone

August 10th, 2008, 05:54 PM

In my ubuntu 8.04 installation the file associations are broken for basically every filetype. If I double click on a file (a jpg for example) it says there's no applications installed for this file type. When right click on the file and do a open with...-> image viewer it works and remembers it. But nautilus doesn't show any preview of picture or video files (not even after I restored the file association with 'open with')
Also I noticed all mp3 files have a executable icon instead of the usual mp3 icon in nautilus.

I tried to create a new user account and login under that but I have the same problem then.

Any ideas what could cause this and how to fix it?

I have noted some other 'weird things' that might be related to the problem:
- If I drag an program from the applications menu to my desktop I get a .desktop file on the desktop with a textfile icon instead of a normal shortcut with an application icon
- On my ntfs partition a lot of files are executables
- All files have default text file or exe icons instead of an icon that fits the file type (picture have picture icons...etc). Also there a no previews available in nautilus (I have set nautilus to make always previews of files up to 100 MB)

Can anybody help me? I'm using ubuntu 8.04 64 bit and I have installed all updates.

I had problem like this some time ago, for more info see this thread (http://ubuntuforums.org/showthread.php?t=868218).

Run this in terminal:
sudo update-mime-database /usr/share/mime
and maybe one more command:
update-mime-database ~/.local/share/mime/
