Detach Icedove from xterm itself called from terminal.

[Paul Isambert <zappathustra@free.fr>]

Hello there,

When started from gnome-terminal, Icedove stays attached to it. I can 
detach it by executing "icedove &".
The problem is, I can't seem to do that recursively, i.e. from the 
terminal call another terminal which calls "icedove &". The following 
works: "xterm -e 'icedove'" (with Icedove attached to xterm), but "xterm 
-e 'icedove &'" doesn't (xterm starts and closes immediately).

Any idea?

Best,
Paul
