gtk-demo execution error (GTK+ 2.0)

["Dongho Shin" <electman acadcorp com>]

Hi, all.

I installed all of the GTK+ 2.0 components (glib-2.0, atk-1.0, pango-1.0, and gtk+-2.0)
successfully, and I executed the gtk-demo program, but it printed the error message below and died:

gtk-demo (pid: 16943): ** ERROR **: file basic-x.c: line 309 (find_converter): 
assertion failed: (cd != (GIConv)-1)

My gdb reported (using 'where' command) the core dumped point like this:

#0  0xef08880c in _kill ()
#1  0xef03a658 in abort ()
#2  0xef1332ec in g_logv (log_domain=0x0, log_level=G_LOG_LEVEL_ERROR,

I can't understand why the address of the 'cache' was changed during transferring from 'conv_8bit' function
to 'find_converter' function. Do you have some clues?

My system is Solaris 2.6 / Sun Ultra 10. And this is South Korea, so the Korean language support
is installed.

Thanks in advance.
Dongho.
