All we are getting is this error:
We apologize for the inconvenience, but we are unable to process your request at this time. Our engineers have been notified of this problem and will work to resolve it. Please note that using your browser's back button in AdWords can increase the likelihood of errors. If you think this was the cause of your error, please try again without using the back button.
As an alternative, you can use the new UI and sort the ads by Status. It doesn't help much if you have a lot of old undeleted/abandoned disapproved ads, though.
I just noticed this thread a few minutes ago, and pinged Engineering. Turns out they are aware of it, and are already on it. I don't have an estimated time-to-fix at this point, however.
My apology for the frustration.
