For example on a .ogg or OpenOffice.org file on my desktop. By right
clicking, I simply mean that I click with the right button of the mouse
on a file to get the contextual menu and then I choose send to... 
option. The problem is that the window that comes just after offers me 
only Evolution as mail client in the Send as field. The same is also 
true when I "right click" on file (say a .txt) within the file browser.
