Bug in chapter detection

Today I looked at my new Vantage Point BD and eac3to reported 51 chapters. This movie has 16 chapters so on a hunch went back to an earlier version of eac3to and sure enough, got 16 chapters. After trying subsequent versions I found that it broke going from v2.65 to v2.66:

Code:
eac3to v2.65
command line: eac3to h:\bdmv\stream\00011.m2ts
------------------------------------------------------------------------------
M2TS, 2 video tracks, 7 audio tracks, 15 subtitle tracks, 1:30:05
1: Chapters, 16 chapters *CORRECT*
2: h264/AVC, 1080p24 /1.001 (16:9)
3: h264/AVC, 480p24 /1.001 (20:11)

A peek at the changelog shows the likely culprit:
Code:
v2.66
* changed eac3to to allow AAC encoding with 7.1 channels (for new Nero encoder)
* fixed AGM creation for files bigger than 4GB
* added support for Nero's new AAC Encoder download URL
* lowered volume of error/success sounds
* when there are 2 similar playlists the one with less chapters is ignored now
Broken all the way to 3.06. Let me know Madshi if I can help in any way to fix it.
