The crash occurred in XGetICValues which is part of the multi-language input (IME) handling in X11. not sure why exactly it doesn't like eu.UTF-8 setting it to "C" would effectively turn off UTF8 which you generally don't want to do.. you want to use a UTF8 locale.. such as en_US.UTF-8.

Now, on my system (Fedora 17). setting the locale to yours does not cause a crash but rather causes it to quit with an error.

Code:
LANG=eo.utf8 ./Launcher.bin.x86_64 

Can't set the specified locale! Check LANG, LC_CTYPE, LC_ALL.

Now, do you have any other lang variables set?? e.g. anything starting with LC_ (set | grep LC_)

Essentially what is going on is I'm initializing the locale with the environment as internally amnesia handles Unicode conversions for text and file paths..

So we do a simple call like this in the startup.

Code:
    if(!std::setlocale(LC_CTYPE, "")) {

                fprintf(stderr, "Can't set the specified locale! Check LANG, LC_CTYPE, LC_ALL.\n");

                return 1;

        }

        char *charset = nl_langinfo(CODESET);

        bool utf8_mode = (strcasecmp(charset, "UTF-8") == 0);

        if (!utf8_mode) {

                fprintf(stderr, "UTF-8 Charset %s available.\nCurrent LANG is %s\nCharset: %s\n",

                        utf8_mode ? "is" : "not",

                        getenv("LANG"), charset);

        }

Which should not fail. (And this is the same code that has been in the Penumbra series, and Amneisa: TDD).. so I'm surprised that there are now issues. And it's rather odd that on Ubuntu setting the locale succeeds only to have the X calls crash later on.

I'll have to investigate more on what is causing this issue.. But you might want to ensure you have the latest updates installed and possible report a bug with your distribution about the issue with that locale.

Yes, I get the same error when I set e.g. LANG=foobar or anything other that is not a valid value for this. But for eo.UTF-8 (upper case, don't know if this matters) it still silenty crashens.

Code:
$ set | grep LC_

LC_ADDRESS=eo.UTF-8

LC_IDENTIFICATION=eo.UTF-8

LC_MEASUREMENT=eo.UTF-8

LC_MONETARY=eo.UTF-8

LC_NAME=eo.UTF-8

LC_NUMERIC=eo.UTF-8

LC_PAPER=eo.UTF-8

LC_TELEPHONE=eo.UTF-8

LC_TIME=eo.UTF-8

    for i in $(LC_ALL=C $prog --help);

    for i in $(LC_ALL=C $prog --usage);

    local LC_CTYPE=C;

            __grubcomp "$(LC_ALL=C $prog --help |                         awk -F ":" '/available formats/ { print $2 }' |                         sed 's/, / /g')";

            __grubcomp "$(LC_ALL=C $prog --help |                         awk -F "[()]" '/--target=/ { print $2 }' |                         sed 's/|/ /g')";

    LANG=C LC_MESSAGES=C svn info --non-interactive 2> /dev/null | while read line; do

But only setting LANG=en_US.UTF-8 is enough to make the game run.

No problems with TDD.
