Export po file BUG on account module, po syntax error

I'm using revision 4465 code.
When i export mn.po file from account module (using Admin->Translations->Import / Export->Export Translation wizard) then generated po file has syntax error.

#. module: account
#: code:addons/account/wizard/account_move_journal.py:0
#, python-format
msgid ""
"Can\'t find any account journal of %s type for this company.\n"
"\n"
"You can create one in the menu: \n"
"Configuration\Financial Accounting\Accounts\Journals.' % (context.get('journal_type"
msgstr ""
"Can\'t find any account journal of %s type for this company.\n"
"\n"
"You can create one in the menu: \n"
"Configuration\Financial Accounting\Accounts\Journals.' % (context.get('journal_type"

My solution to fix this error :
addons/account/wizard/account_move_journal.py line 54:

- raise osv.except_osv(_('Configuration Error !'), _('Can\'t find any account journal of %s type for this company.\n\nYou can create one in the menu: \nConfiguration\Financial Accounting\Accounts\Journals.' % (context.get('journal_type'))))

+ raise osv.except_osv(_('Configuration Error !'), _("Can't find any account journal of %s type for this company.\n\nYou can create one in the menu: \nConfiguration\\Financial Accounting\\Accounts\\Journals." % (context.get('journal_type'))))
