xdg-open doesn't recognise Lubuntu's DESKTOP_SESSION value

[bluearcus]

Binary package hint: xdg-utils

Many applications rely upon xdg-open, particularly chromium, for opening folders in the DE. xdg-open looks for 'LXDE' as the DESKTOP_SESSION environment variable value to determine that an LXDE session is running, and that pcmanfm should be used as the default file manager.
Unfortunately, Lubuntu's package mantainers, in their wisdom, have arranged for the DESKTOP_SESSSION value to be set to 'Lubuntu', which is not recognised by the xdg-open script. xdg-open needs to recognise either value as symbolising an LXDE session, or alternatively, the Lubuntu maintainers need to revert to the standard LXDE value.

This is not a duplicate of bug #779156.

#779156 has reported that chromium uses xdg-mail and xdg-mime incorrectly when in Lubuntu. Patches have been generated to fix the problem only in these two scripts.

In this bug, the problem is within xdg-open, when attempting to open a filesystem path using the filemanager. The same form of fix as in the other bug needs applying, but to xdg-open.

Please ensure the fix is also applied to xdg-open.

I tried xdg-open /tmp/ under Lubuntu, and /tmp/ is opened correctly in pcmanfm. If it's not related to bug #779156, it's probably fixed. If not, please provide a way to reproduce the problem.
