QTranslator::load() used to: - call find_translation(), which finds the file, ensures it's readable, and returns file name - pass the file name to do_load() which would proceed to open the file During the time between calling find_translation()/is_readable_file() and calling do_load(), the underlying filesystem could have changed. Solve the issue by making find_translation() call do_load() itself (as suggested in the bug report). Also rename the method to load_translation() and make it a member method so that it can call do_load(). Remove the now redundant is_readable_file() static helper, since QFile::open() in do_load() will do the necessary checks. Note that there is a slight behavior change: - with this commit we call do_load() on a variant of the translation file name, if that fails we call it again on the next variant ...etc - before this, if the file was readable, the code called do_load() once, if it failed, it didn't try again. This was suggested by Volker in code review as a good/welcome side-effect.
