Hi.
After a few days searching for the errors, we successfully run the server after Linux system (Debian exactly). We found that the error is in the "blocks.xml" file and one of the letters has a bad size ("mods" instead of "Mods"). Unix_like systems do not like it
Additionally needed a setting propertly locales, on some systems.
Ok, we put small fix (as .tar.gz archive) on this site or you can edit manually needed files. These changes are working for us.
Good luck!
