If you provide a test case of something that's handled poorly, and open
a bugzilla with that, we'd definitely help with that. It seems to me
the tutorial providing a zip file you can import would make life easier
as well. A bugzilla suggesting that's a good idea.

Well, yes, we don't expect the failure, so we log the problem but need
to change the code to not have the problem.

Just keep in mind that I need to be able to reproduce each problem so a
test case of some sort (doesn't have to be your proprietary code) is
essential. Sometimes people send me their code directly so I can use it
to fix the problem without them having to share that code with the
community at large.
