Chromium “Show in Folder” opens in text editor

(Using ubuntu 11.04)

I tried to open a torrent file in chrome, and it asked for my default application, so I clicked Transmission, and then I got an error: "Failed to execute default file manager, Failed to execute child process "transmission" (No such file or directory)."

Now if I click on any shortcut on the unity bar, such as the trash folder or the icon for my portable hard drive, I get this error, as well as with any download or folder from chrome or firefox. I can't seem to figure out how to fix this, as there seems to be no easy way to do it.

I hope I can answer this with an answer I posted a while back here Chromium "Show in Folder" opens in text editor (That would make this a duplicate so it might get closed ;) )

In ~/.local/share/applications/mimeapps.list there is a list of files to be opend by an application. Have a look with more ~/.local/share/applications/mimeapps.list and check if you can find something weird here. You can use vi or gedit to edit this file.

But there is also a command mimeopen that allows you to alter what program should open what file (and that updates the file I mentioned before). It will 'guess' what would be the most logical option based on the file you feed it.

mimeopen -d /home/{your_name}/Documents
Please choose a default application for files of type inode/directory

    1) Open Folder  (nautilus-folder-handler)
    2) Other...

mimeopen -d \[Mazui\]_Ore_No_Imouto_-_14_\[SD\]\[7EA51F50\].mkv 
Please choose a default application for files of type video/x-matroska

    1) Enqueue in SMPlayer  (smplayer_enqueue)
    2) Movie Player  (totem)
    3) SMPlayer  (smplayer)
    4) Banshee  (banshee)
    5) VLC media player  (vlc)
    6) Other...

Same works for a torrent file and any other file.

Maybe you already know this but if you can not get to command line use control-alt-f1 and log in with your sudo user account and password. control-alt-f7 gets you back to your desktop.
