Mint 13 LTS
Mate 1.4 (from backports ppa)
Had a custom menu entry like this:
mate-terminal --title Host --execute ssh -2 -Y host.example.com
Worked fine. Modified it to look like this:
mate-terminal --title Host --execute ssh -C -c blowfish -2 -Y -L 57000:host.example.com:57000 host.example.com
No longer worked. Terminal would flash up briefly and disappear.
Along the way I discovered that changes to Mate menu entries appear to often go unnoticed by Matemenu unless you delete and re-create the entry or log off and back on. Very annoying.
Finally solved it by putting the line in a one-line shell script and putting the name of that script into Matemenu.
The line in question, btw, worked fine with Gnome 2 and gnome-terminal under Ubuntu 10.04 LTS and (?) 9.10.
