Racco,

on your development server can you ser this in the file class.t3lib_db.php?

        // Debug:
    var $debugOutput = TRUE;        // Set "TRUE" if you want database 
errors outputted.
    var $debug_lastBuiltQuery = '';        // Internally: Set to last 
built query (not necessarily executed...)
    var $store_lastBuiltQuery = TRUE;    // Set "TRUE" if you want the 
last built query to be stored in $debug_lastBuiltQuery independent of 
$this->debugOutput

It should show you the complete URL etc... I get something simular but 
isn't harmfull (so far) so we can compare and solve...

cheers,
Ries
