Sorry, I get it now: good revisions should be marked as "bad".
Thanks for your help :)
So I ran a git bisect with my script, here is the bisect log:

The commit that introduced the change is this one:
{{{
commit 194be1f43ea391eb986732707435176e579265aa
Author: Anton Khirnov <an...@khirnov.net>
Date: Sun May 18 12:12:59 2014 +0200
lavf: switch to AVStream.time_base as the hint for the muxer timebase
Previously, AVStream.codec.time_base was used for that purpose, which
was quite confusing for the callers. This change also opens the path
for
removing AVStream.codec.
The change in the lavf-mkv test is due to the native timebase (1/1000)
being used instead of the default one (1/90000), so the packets are
now
sent to the crc muxer in the same order in which they are demuxed
(previously some of them got reordered because of inexact timestamp
conversion).
