What lintian complaint do you see?  When i built it originally back in
december, there was no lintian complaint.

When i build it today, I see:

W: python3-notmuch2: python-module-in-wrong-location usr/lib/python3.8/dist-packages/notmuch2/ usr/lib/python3/dist-packages/notmuch2/
W: python3-notmuch2: python-module-in-wrong-location usr/lib/python3.8/dist-packages/notmuch2/_capi.abi3.so usr/lib/python3/dist-packages/notmuch2/_capi.abi3.so

in the older package, i see only one copy of the .so, but in the version
built today, i see two copies (i think identical):

0 dkg at alice:~/src/notmuch/notmuch$ dpkg --contents ../python3-notmuch2_0.29.3+109~gef0d513+1_amd64.deb | grep so$
-rw-r--r-- root/root     73616 2019-12-23 17:23 ./usr/lib/python3/dist-packages/notmuch2/_capi.abi3.so
0 dkg at alice:~/src/notmuch/notmuch$ dpkg --contents ../python3-notmuch2_0.29.3+111~g4c95a79+1_amd64.deb | grep so$
-rw-r--r-- root/root     73784 2020-01-10 15:10 ./usr/lib/python3/dist-packages/notmuch2/_capi.abi3.so
-rw-r--r-- root/root     73784 2020-01-10 15:10 ./usr/lib/python3.8/dist-packages/notmuch2/_capi.abi3.so
0 dkg at alice:~/src/notmuch/notmuch$ 

during the more recent build, i also see this warning from dh_python3:


W: dh_python3 fs:112: Paths differ: debian/python3-notmuch2/usr/lib/python3.8/dist-packages/notmuch2/_capi.abi3.so and debian/python3-notmuch2/usr/lib/python3/dist-packages/notmuch2/_capi.abi3.so


I confess i don't really understand what happened to change this, since
the package should be almost exactly the same source.

comparing the .buildinfo files, i see a few minor version changes that
might be relevant:

- python3 (= 3.7.5-1),
+ python3 (= 3.7.5-3),

- python3-all (= 3.7.5-1),
+ python3-all (= 3.7.5-3),

- python3.7 (= 3.7.5-2),
- python3.7-minimal (= 3.7.5-2),
- python3.8 (= 3.8.0-5),
- python3.8-minimal (= 3.8.0-5),
+ python3.7 (= 3.7.6-1),
+ python3.7-minimal (= 3.7.6-1),
+ python3.8 (= 3.8.1-2),
+ python3.8-minimal (= 3.8.1-2),

- debhelper (= 12.7.2),
+ debhelper (= 12.7.3),

they were both built with dh-python 4.20191017)

but none of these changes ought to warrant shipping an extra copy of the
.so file.

So i'm a little bit confused about what happened here. :/

agreed.
