I think the fix is just some typos in SMW_Factbox.php, this make the error handling like other code:

--- .	(revision 21705)
+++ .	(working copy)
@@ -188,8 +188,8 @@
 
 		if (NULL != $error) {
 			$datavalue = SMWDataValue::newTypedValue(new SMWErrorTypeHandler($error),$value);
-			if (!$smwgStoreActive) {
-				SMWFactbox::$semdata->addSpecialValue(SMW_SP_IMPORTED_FROM,$result);
+			if ($smwgStoreActive) {
+				SMWFactbox::$semdata->addSpecialValue(SMW_SP_IMPORTED_FROM, $datavalue);
 			}
 			return $datavalue;
 		}

I'm not sure about the check for smwgStoreActive but it works for me so I checked this in (SVN revision 22499).

Thanks. There were more of the same typos in earlier versions, but this one escaped my fixes. It should be correct now.
