(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.
