xterm in X.org error with some locales?

[Jie Gao]

Hi, all

I switched to Xorg on 5-CURRENT yesterday, following the steps in 
/usr/ports/UPDATING and portupgraded everything. Everything works just 
fine except one thing: xterm has some error on some particular locales. 
The symptom is like this:
 
  # setenv LANG zh_CN.eucCN
  # xterm

After this, xterm's window only quickly flashed out and then 
disappeared. I tried various locales, mainly zh_CN.* ones, finding that 
zh_CN.eucCN, zh_CN.GB2312 and zh_CN.GBK all make xterm a splash.

I cannot tell what's wrong because I can find corresponding error 
information nowhere. I checked console, /var/log/messages, 
~/.xsession-error and /var/log/Xorg.0.log. None of them contain relevant 
messages.

Any ideas and suggestions?
