in case your admins and editors use the default language for wordpress, than all that languages menus can be a little cluttering
and Adminimize, for instance, is not able to hide them
it's possible to block this behavior with this little mod in qtranslate_configuration.php
add a return in line 28 (which is empty)
/* Language Switcher for Admin */ ---> this is line 27
return;
it'd be nice if this feature was included in the plugin interface
