If you file the issues yourself, you can show to everyone else that you're working on them. That's exactly the kind of communication ST is lacking. Plus, you'll learn about bugs you didnt encounter, so they can be fixed (by you or others) before you have to hit them yourself.
Give the guy a chance to write a functioning editor first. I'm sure he'll reconsider opening up the issue tracker after the thing is actually useful, and maybe has a few more contributors to share the load.
No one is entitled to anything with open source, not even support or a bug tracker. The author is trying to provide an open source alternative to a closed source product controlled by an uncommunicative company. He deserves support and help, not people telling him what to do.
