15776,get_category_parents produces fatal error,tar.gz,,"On a test install of WP 3.1 [16732], I notice that this function is broken: it produces an error when called inside the single post template. 

Using this code :
{{{
<?php echo get_category_parents($cat, TRUE, ' &raquo; '); ?>
}}}
produces the following error message: ''Catchable fatal error: Object of class WP_Error could not be converted to string in (.../themes/twentyten/loop-single.php)''. This effects every post.

I did not spot this error in 3.1-beta1-16723, so I believe it has been introduced after that build.

To rule out any error in my custom theme, I tested it with the ''Twenty Ten 1.3-alpha'' theme, adding the function above inside ''loop-single.php'' (at line 32, just above the content). It produces the same error message.
