mtree, joomfish and sef advanced

I'm using mosets tree, joomfish and sef advance.

Joomfish is supported, but not joomfish functionality.

I tried the following hack, and the translated category names are displayed.
forum.mosets.com/showthread.php?p=16640#post16640

However, the linking doesn't work when sef advanced is switched on.

Maybe the solution can be found in the sef_ext.php file?

Any help appreciated.
