Interesting bug.
I think you should file it. It will help to have the details documented and it might be useful for someone in the future.
However, it isn't a supported scenario for Alfresco, so I won't be assigning it to an engineer for us to fix. I will mention it to engineers that I think might be interested, and if they don't see an immediate change they can make I will need to close it as "Not a Bug".

Thanks for bringing it to our attention.
