In 6000.3.8f1 the error will also -sometimes- be accompanied by:
Leak Detected : Persistent allocates 1 individual allocations. To find out more please enable 'Preferences > Jobs > Leak Detection Level > Enabled With Stack Trace' and reproduce the leak again.
It's as if I were using Jobs/Burst, despite the fact that there isn't a single instance of Jobs/Burst being used anywhere in this project. This warning only ever accompanies the error triggered by this bug, and only appears sometimes.
