Confirming for 32bit:

When starting MCC with 

LANGUAGE=pt_BR mcc

and clicking on the icon to select msec-gui, I get a message "Este Programa não foi Encerrado Corretamente"

Starting the tool directly fails. too:

[root@Mga5_32bit marja]# LANGUAGE=pt_BR msecgui 
INFO: Starting gui..
Traceback (most recent call last):
  File "/usr/share/msec/msecgui.py", line 1789, in <module>
    gui = MsecGui(log, msec, perms, msec_config, perm_conf, exceptions, embed=PlugWindowID)
  File "/usr/share/msec/msecgui.py", line 173, in __init__
    self.reload_config()
  File "/usr/share/msec/msecgui.py", line 457, in reload_config
    self.exceptions.load()
  File "/usr/share/msec/config.py", line 319, in load
    self.log.info(_("loading exceptions file %s: %s") % (self.config, sys.exc_value[1]))
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 16: ordinal not in range(128)
[root@Mga5_32bit marja]#

Which character on that line has position 16? The "i" in "arquivo"? At first sight, I see nothing odd.
  #: ../src/msec/config.py:319
  msgid "loading exceptions file %s: %s"
  msgstr "Carregando arquivo de exceções %s: %s"


Starting it with LANGUAGE=pt msecgui doesn't give an error.

The following error is valid for pt.po, too, so probably unrelated:

  [marja@Mga5_32bit ~]$ LC_ALL=C msgfmt -c -v mgagit/software/msec/po/pt_BR.po 
  pt_BR.po:19: warning: header field 'Content-Transfer-Encoding' still has the
  initial default value
  318 translated messages.

Summary: msec-gui: error message and does not work => msec-gui: error message and does not work ('ascii' codec can't decode byte 0xc3 in position 16)

I think we can't force translators to change string(s) to the ASCII encoding.

At least until Thierry decide. I hope that I'm right about that he maintain the package. At least I see in madb that he mostly commit to it. Feel free to reasign.

I don't think that's the problem, even if I don't understand what is, except that there is a good chance it is something in the pt_BR po file (but maybe a different line than I first thought)

CC'ing Yuri who might understand whether anything is wrong with pt_BR.po (note that I made some changes that might not have been copied to Tx).

Also CC'ing papoteur, who knows python and might be able to tell where the following points to:
    File "/usr/share/msec/config.py", line 319, in load
    self.log.info(_("loading exceptions file %s: %s") % (self.config, sys.exc_value[1]))

(it is maybe a translation for the target that contains an error, instead of the translation for "loading exceptions file %s: %s"?
.... grep -r "sys.exc_value" software/msec/* gives many lines that contain a translatable string)

Btw, what is the command to get all lines in a po file wrapped at 79 characters (including getting any """ added or moved where needed)?

It is hard to check the current pt_BR.po, because it contains some very long lines :-/
