[Pkg-roundcube-maintainers] Bug#1037537: Upgrade To Bookworm Fails with Roundcube Update

[Bryan K. Walton]

Package: roundcube-core
Version: 1.6.1+dfsg-1

Today, I tried to upgrade my webserver to Debian 12.0 (bookworm).
Everything succeeded but Roundcube.  The upgrade of Roundcube fails with
the following:
