Nico, ok, running openbox-session when there's already some session running seems to open all the apps listed in openbox's autostart.sh so maybe someone would use that...(although maybe a desktop file for that isn't really needed...). But please update /usr/share/xsessions/openbox.desktop with the file I sent in the bug report that includes the Brazilian Portuguese translation.
Also I see that you're one of the maintainers for obconf. I translated it to pt_BR (see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=607492 ; note that an updated obconf.desktop is also included). I sent the translation as a bug report upstream but it seems the project is abandoned because the developer ignored it and also other bug reports with translations for other languages. If you add the translations for obconf into the Debian package it would be very nice. I'll find the bug reports upstream and send you the links anyway just in case you accept. Regards.
