bash script problem when run from desktop launcher

Question

I have a script which does the following:

1. Connect via sshfs to a directory on a server
2. Within that directory, there is an encrypted volume. Open it to the device mapper.
3. Mount to a local directory (-o rw & -t ext4)

When I run this script from the terminal

sudo /.../myscript.sh

it runs with the expected behaviour. However, when I run this script from a desktop shortcut, it runs, but with problems. In particular:

1. It appears to be mounted, and I can 'cd' into the mounted directory and list the contents. However, when I try to list the contents of a subdirectory, I get this message:

   ls: reading directory .: Input/output error

2. I don't seem to have write access to the directory. (I can't save files)

My desktop entry looks like this: (... is just for simplicity, again)

[Desktop Entry]
Name=myscript
Exec=mate-terminal -e "sudo /.../myscript.sh"
Terminal=false
Type=Application

Can anyone suggest why running the script from the shell seems to work, but running from the desktop shortcut gives me problems?

Doesn't gksudo /.../myscript.sh do everything you want (assuming you're running Gnome)? – Ken Sharp

... actually that does seem to work! Looks like this is an example of the mysterious problems mentioned here http://www.psychocats.net/ubuntu/graphicalsudo
