Please provide a test case and your complete Eclipse ".log" file.

It would also be good to see your config details from the Eclipse About dialog.

You should resubmit the case using the "Contact Support" button in the error window.

I have emailed the address listed under the support section of the website with all the information you have asked for.

I have just resubmitted using the contact support. If you could further advise me on how to access the Eclipse About Information, that would be great.
