gnome-session-properties: Running a script in a subdirectory with spaces in name is not possible

Workaround

The workaround is simple. Edit the file ~/.config/autostart/nice.desktop directly (the file might be called different when viewed with nautilus, like "No name").

Now everything is like normal and next lines with both work:
        sh "/home/jdo/Scripts and Settings/Bash Scripts/startup.sh"
        sh /home/jdo/Scripts\ and\ Settings/Bash\ Scripts/startup.sh

But I have to remember not to press the 'edit'-button on that line in the 'start program'-tab of the gnome-session-properties. The gnome-session-properties do indeed translate the text: all double and single quotes and backslashes are removed. And that is the problem.
