Code tries to access object as array --> yields fatal error

error message:
Fatal error: Cannot use object of type stdClass as array in […]\sites\all\modules\drupal-contrib\i18n\i18n.module on line 245

This error had also occured in beta2 in line 264.

the function containing line 245 reads:

243 function i18n_language_property($code, $property) {
244   $languages = language_list();
245   return isset($languages[$code][$property]) ? $languages[$code][$property] : NULL;
246 }

Reason:
i18n tries to access a language object as array.

Solution:

245   return isset($languages[$code]->$property) ? $languages[$code]->$property : NULL;
