chapter selection ignored when using vapoursynth

Looking at the Vapoursynth script:

# Imports
import os
import sys
import ctypes
# Loading Support Files
Dllref = ctypes.windll.LoadLibrary("C:/utils/video/Hybrid/Hybrid/64bit/vsfilters/Support/libfftw3f-3.dll")
import vapoursynth as vs
core = vs.get_core()
# Import scripts folder
scriptPath = 'C:/utils/video/Hybrid/Hybrid/64bit/vsscripts'
sys.path.append(os.path.abspath(scriptPath))
# Loading Plugins
core.std.LoadPlugin(path="C:/utils/video/Hybrid/Hybrid/64bit/vsfilters/GrainFilter/AddGrain/AddGrain.dll")
core.std.LoadPlugin(path="C:/utils/video/Hybrid/Hybrid/64bit/vsfilters/DenoiseFilter/FFT3DFilter/fft3dfilter.dll")
core.std.LoadPlugin(path="C:/utils/video/Hybrid/Hybrid/64bit/vsfilters/DenoiseFilter/DFTTest/DFTTest.dll")

# Import scripts
import havsfunc
# Loading D:\rips\standa\VIDEO_TS using D2VSource
clip = core.d2v.Source(input="D:/temp/18_31_50_3010.d2v")
# making sure input color matrix is set as 709
clip = core.resize.Point(clip, matrix_in_s="709",range_s="limited")
# making sure frame rate is set to 29.97
clip = core.std.AssumeFPS(clip, fpsnum=30000, fpsden=1001)
# Setting color range to TV (limited) range.
clip = core.std.SetFrameProp(clip=clip, prop="_ColorRange", intval=1)
# cutting from 0 with 12748 frames - WARNING: This might cause synch issues
clip = core.std.Trim(clip=clip, first=0, length=12748)
# setting field order to what QTGMC should assume
clip = core.std.SetFrameProp(clip=clip, prop="_FieldBased", intval=1)
# Deinterlacing using QTGMC
clip = havsfunc.QTGMC(Input=clip, Preset="Fast", TFF=False)
clip = clip[::2]
# Output
clip.set_output()

I see no direct problem.
-> Does the Vapoursynth Preview work properly?
(side note: most NTSC DVDs should not be handled with QTGMC since it's meant for interlaced not telecine content)

The encoding call:

"C:\utils\video\Hybrid\Hybrid\64bit\VAPOUR~1\vspipe.exe" "D:\temp\encodingTempSynthSkript_18_31_50_3010.vpy" - --y4m | "C:\utils\video\Hybrid\Hybrid\64bit\x264.exe" --preset veryfast --pass 1 --bitrate 1500 --profile high --level 4.1 --direct auto --b-adapt 0 --sync-lookahead 33 --qcomp 0.5 --rc-lookahead 40 --qpmax 81 --aq-mode 0 --sar 8:9 --non-deterministic --range tv --stats "D:\temp\DVD_new_new_new_18_31_50_3010_03.stats" --demuxer y4m  --input-range tv --fps 30000/1001 --output-depth 8 --output NUL -

looks fine too, but judging from the error message there is some problem witht he Vapoursynth script.

I tried to reproduce the issue here, but couldn't.
