[Pkg-matrix-maintainers] Bug#999903: python3-olm: python import fails undefined symbol: olm_account_fallback_key

[Kyle Robbertze]

Package: python3-olm
Version: 3.2.1~dfsg-7
Severity: grave
Justification: renders package unusable

Dear Maintainer,

Applications are unable to import olm due to the following error:

> Traceback (most recent call last):
>   File "<stdin>", line 1, in <module>
>   File "/usr/lib/python3/dist-packages/olm/__init__.py", line 24, in <module>
>     from .utility import ed25519_verify, OlmVerifyError, OlmHashError, sha256
>   File "/usr/lib/python3/dist-packages/olm/utility.py", line 39, in <module>
>     from _libolm import ffi, lib  # type: ignore
> ImportError: /usr/lib/python3/dist-packages/_libolm.abi3.so: undefined symbol: olm_account_fallback_key

A simple test case is to run python3 -c "import olm". This renders
python3-olm unusable on stable

Thanks
Kyle
