View source for Application missing in ''Select Application'' dialog

'''Problem:'''

You would like to open a file of a specific mimetype with a specific application and the ''Select Application'' dialog box (''Open with'' > ''Other application...'') does not show the desired application. Since Gnome 3 it is not possible anymore to manually enter a startup command.

'''Solution:'''

Check that a correct ''.desktop'' file for the application exists. This means the line ''Exec=...'' has to include ''%f''.
If this is not the case, copy the file from ''/usr/share/applications'' to ''~/.local/share/applications'' and add '' %f'' to the end of the ''Exec=...'' line.
