Hi all, here is a workaround, I used for kali-linux. OK, so, as the code was not changed, as Andriy told, here is a workaround, if someone wants to build a kali-live-image with LXDE.
1. Download libfm-extra4-1.2.4-1 for your architecture from http:// http.kali.org/kali 2. Extract the package by using dpkg-deb. 3. Edit debian/control and change the version from 1.2.4-1 to a higher version than 1.2.5-1 (I am using 1.2.5-2, as it is close to the prior version). 4. Repack the package again by using dpkg-deb. 5. Copy the new libfm-extra4-1.2.5-2.deb to ~live-build-config/config/packages- chroot/ 6. Now build the new image. After booting it (either from CD, or as in my case from an USB-Stick), you see, the menus in LXDE are back! Yeah! Maybe Debian wants to use this way to get a running version in its repo. Sorry, that I built only for i386, but at the moment I have no amd64-computer at hand (sadly my notebook died 3 days ago. Mainboard dead!) Hope this helps. Happy hacking Hans
