Catchable fatal error with pic upload

Dear WP Forum

I just installed wp 2.7.3 and I’m trying to publish an article without Windows Live Writer.

If I upload a picture with the media feature within the ADD NEW article, i can load it in and set the display option, but when i get to import it in the actual text of the article, i get this error:

Catchable fatal error: Object of class stdClass could not be converted to string in /web/htdocs/www.partireper.it/home/wp-includes/wp-db.php on line 429

Is there anything i can do to fix this?

Regards.
