Ubuntu – Unable to choose default application


I just upgraded to Ubuntu 11.10 and wanted to set up .z4 files so that they would be opened by gargoyle-free (as an example) although gargoyle-free is not an option in the default application list that arises from the context menu. It used to be possible to manually enter a default application directly from the dialog, however the feature seems to have been replaced by a simplified (and unfortunately useless) "Find application online" button. Is there perhaps a new way to do this that doesn't involve messing with the command line?

Some applications (like clementine audio player) aren't listed in "Other Applications".

Right click on the file you want to open, select Properties, go to tab Open with.

If the application you want to use to open a file is not listed on the program list select Other Applications and press the button Add.
