ID 273520 - Particle VectorBlur not applied to last frame of a particle's life and causes crash on Windows

Problem summary
Particle VectorBlur not applied to last frame of a particle's life and causes crash on Windows

Customer reported version
nuke.10.5v1

Customer reported platform
10.12

Steps to reproduce
1. Open Nuke
2. Open customer script
3. View VectorBlur node
4. View Grade node
5. Compare between the two on the same frame
Result: Particles which only have a single frame of life left do not have the vector blur correctly applied, so they appear as a single dot, rather than blurred

Workaround
Unknown. If known please add steps to workaround or avoid the problem

Reproduced by support
Nuke 10.5v3 - OSX 10.11.6
Nuke 10.0v1 - OSX 10.11.6
VectorBlur node did not exist before 10.0v1

Script crashes Nuke on opening in:

Nuke 10.0v5 - Windows 8: 072a786e-79ec-4f6f-9bd2-8d5697350729
Nuke 10.0v1 - Windows 8: 85841098-4a01-417f-b11c-ad9a2804d10d

VectorBlur to still apply to last frame of particle life

Actual behaviour
VectorBlur not applied to last frame of particle life
