Dear Jeremy,
this is a known issue, and basically a worksforme.
Since we use SAX, and the processing is incremental, to augment the users
percieved performance and decrease memory usage we send the results as soon
as they are ready.
This means that the error happens when partial results are already
committed, and error info can only follow already committed output.
If you want you can change the error stylesheet to have inside a javascript
that redirects the user to a clean error page, or simply output a <p> tag
that says that an error occurred.
If you have a better solution, please commit it, we are all waiting.
