I have the same problem, using the Esperanto (EO) localization.
The file /usr/share/info/dir for EO also has some problems, but I noticed that the big deal is with the line containing the Top node reference.
Instead of a '\t' symbol, there should be a real tab character. So, you may simply edit it and substitute the '\t' for a TAB.
But, as seldom we find some translated info manual, I had to stick with the "LANG" solution indicated before, so that I have all manuals in English.
