Resolution Note:
I can't repro this bug, and neither could Unity's CQA team.
We don't know if it's a user project that contains special conditions that makes it crash, or something that's true of every project. Please provide a project that makes the bug reproducible, along with repro steps that are more precise than "do A or B with any asset", which clearly if this was making Unity crash consistently, then Unity would be completely unusable.
Also, please specify what exact version corresponds to the line numbers in the call stack provided. I will assume it's 6000.3.0a3.
