Patch by Zarafa <http://www.zarafa.com/> - on Debian machines, you need to configure the locales
(languages) that will be used on the system. When you use a locale (eg. 'LC_MESSAGES=nl_NL', but did not
configure your distribution to have this locale present on your system, a NULL pointer would have thrown
an exception in the std::string class. This makes sure that exception never happens.
