I would say you have a very unusual configuration in production. It's been two years, it's hard to believe there's anything supported we're not handling since nothing like this has come up.

File a bug and attach all the relevant files. If the issue turns out to be an error in your file, it will just be closed out there with the explanation. Either way, you're not going to get it to load any time soon, so something has to change.
