Thanks for reporting the bug. Actually, you should not use a throw-away e-mail address, but use one that you read regularly. What if I need you to test something or try out a fix? What if I need additional logging output? You can only provide this to me if you monitor a bug (or get notified via e-mail).

Bug trackers are really an important tool for developers, and it's not just "drop your report in there", but rather a tool for communication between users and developers. It also helps planning features and getting an overview of the current status of the application.
