boost_cache_set not getting the correct url alias

Oki, i just realized how stupid i was.
The problem is that in "boost_cache_set" function both 'drupal_get_path_alias' and 'drupal_get_normal_path' return the same path - 'node/nid' when in fact drupal_get_path_alias should return the alias of the node...
I'll digg into this more and i'll post the results here.

Oki, i think i found what the problem was: in a multilanguage site you must pass the current lang path to 'drupal_get_path_alias' and 'drupal_get_normal_path' functions.
So instead of:

$alias = drupal_get_path_alias($path);
$path = drupal_get_normal_path($path); // normalize path

the code should look like this:

$lang_prefix = language_initialize()->prefix ? language_initialize()->prefix : '';
$alias = drupal_get_path_alias($path, $lang_prefix);
$path = drupal_get_normal_path($path, $lang_prefix); // normalize path

At least for me it works. Please tell me if this makes any sense to you.
Thanks

Corrected the title
