std::ostream/stringstream will use the current locale to determine the numeric formatting. If the locale uses grouping then thousands separators will be inserted in the output which produces an invalid color string in UIConfiguration::reset_gtk_theme() and when converting colors to strings in UIConfiguration::store_color_theme() This has not been a problem so far because it appears that LocaleGuard does not reset the LC_NUMERIC value for the global C++ locale. So if a LocaleGuard is created at any time before these functions are called(even if it goes out of scope) the numeric formatting used by std::streams will use the "C" locale formatting facets.
