lx menu opening empty lxterminal for .desktop icons with Terminal=true
we noticed lauchpad bug # 975152 and worked around it in r11499 for desktop icons, but it seems it happens from the menus too.
not sure, maybe we need to edit the C code and rebuild the lx menu package to solve that? will consult the launchpad ticket..
e.g. GRASS fails to start from the Education menu.
