Sebastian

This part seems to be fixed now but there are two failing tests now when
building with openssl 4.0.

We believe that the bug you reported is fixed in the latest version of
libp11, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1138471@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
