I'm seeing basically the same thing.
I'm running the trial version of 6.03 (my order is pending) with mySQL 4.0.18. A link to phpinfo() on my site will be sent to you, Brian, via PM, along with access to see what's going on and the SQL insert statement for the offending event.
When I added the event this morning, it went to the page that says the database has been updated, like it should. It then meta-refreshed to a zero sized reply error page. At this point, trying to go to any page within the events admin results in zero sized reply. The setup admin and the main escal/ script are unaffected.
At first I thought it was somehow due to the phpsessid, because I could get the login page back up by deleting the cookie. Once the cookie is set again, zero-sized reply again. However, I then found this thread and tried deleting the newly added event using phpmyadmin. Voila! I was able to administer my events again. I then re-added the event, and was faced with zero-sized replies.
The event date was for Feb 7, 2005.
Oh, FWIW, I have only 6 events, plus the offending event. The offending event currently has an id of 12. Changing that id to 5 (no other event has that id) does not affect the problem.
