Summary0003450: Path simulation crashes with unusual setups.
DescriptionUnder certain reproducible situations, the simulator will fail and cause FreeCAD to segfault. These conditions aren't typical but also not very rare.

Two that I've found:
Attempting to simulate with no operations in the Job.
Attempting to simulate with only a custom operation in the job.
Steps To ReproduceCreate a job.
Add NO operations.
Click the Simulator button.
Click either ok or cancel.
freecad segfaults.
TagsNo tags attached.
