Transmission won't start in Startup Applications

[Robert Spanjaard]

I've added Transmission to my Startup Applications by entering

   transmission-gtk -m

as the executable, with -m to start minimized.
This command works fine from a terminal, but it refuses to start from the 
Startup Applications list. I also tried entering

   /usr/bin/transmission-gtk -m

but it still won't start when I log in. What am I doing wrong?
