Comment 5 for bug 83142

I saw the comment just above the commented lines. It explains why they were commented, but doesn't justify the commenting. As you can see here:

http://www.unicode.org/cldr/data/charts/summary/eo.html
http://www.loc.gov/standards/iso639-2/php/code_list.php

the code "eo" for the language Esperanto is a valid one, even if the GNU C Library doesn't support it; anyhow, libx11 doesn't need "eo" to be supported by glibc, otherwise, when those lines are uncommented, things would break somehow, and that doesn't occur.

As for the "XX" territory, see:

http://unicode.org/reports/tr35/tr35-6.html

and search for territory_code, twice, and you will see that XX is a code allowed for private use, which is the case, since Esperanto is a language that doesn't necessary belong to a specific territory. As state on that page, ZZ would be a valid code also.

And, finally, what I just wrote on

https://launchpad.net/ubuntu/+source/gdm/+bug/84011

is valid for this bug too: I think I installed all the necessary packages, but the bomb icon doesn't appear, and I don't know what to do to generate the backtrace you need.
