Language error

[rramirezb]

I am trying to install a language module, but when I try to insert a new language in the admin area (template selection) shows the message:
"Catchable fatal error: Object of class queryFactoryResult could not be converted to string in /home/conillete2/domains/mcjoyas.es/public_html/admin/includes/functions/html_output.php on line 333"
any help?
Thanks

Sorry again for last message, don't take care.
It seems that my brain does not work well today.
