hi, this is not so much a bug, than just a simple missing feature.
qtranslate works perfectly, but there is that small missing feature.
When one creates a custom link in the menu:
the url is not updated to include &lang=xx (if one is viewing the website in a different language than the default one obviously ;) )
I guess it just needs another line in qtranslate_hooks.php to add the proper filter, but i don't know what's the name of the filter for custom menu links?
