[Debian-med-packaging] Bug#1055687: khmer ftbfs with Python 3.12

[Olivier Gayot]

Hi,

Thank you for uploading 3.0.0~a3+dfsg-6!

I was about to request a sync in Ubuntu. Sadly, I noticed that I forgot
to forward one change that was done as an intermediate upload in Ubuntu.
The change is required for Python 3.12 support. Sorry about that!

I've just opened https://salsa.debian.org/med-team/khmer/-/merge_requests/1
with the missing bits to correct the mistake.

Best regards,
Olivier
