"Specific to the locale/po/es_AR.po; it was found by a process that
the Debian Internationalization Team has  that a check of that file
found 12 fatal "duplicate message definition" errors. I ran the command
myself and confirmed it.
I took a look at the file and what it appears to be is that some
msged/msgstr lines somehow ended up being duplicated to other parts of
the file. An example ("Add Warehouse"/"Agregar Deposito"):
locale/po/es_AR.po:2880: duplicate message definition...
locale/po/es_AR.po:350: ...this is the location of the first definition"
I originally wrote this using gedit so I was unaware of the repeated keys. Using poeditor, when tried to save the file, it reported 12 repeated keys. I took note of that ones and remove them one by one. Last time it saved without errors, I think that is ready to go.
