Comment 56 for bug 515386

with the following patch "simple-scan" -> "Email" works correctly on Ubuntu 14.10 again:

the first change makes sure that only the first occurrence of Exec in thunderbird's desktop file is considered: | head -n 1.
the second change is a fix for what is clearly a bug (having $browser instead of the correct variable $desktop).
