Dear Maintainer,

In Debian 12, with PHP 8.2, clicking the "New Contact" button just leads to an
empty page.

I can see that /horde/turba/add.php returns 500, but there is no response.

The only error I found was

2024-02-21 10:12:42: (mod_fastcgi.c.449) FastCGI-stderr:PHP Fatal error:  Declaration of Horde_Form_Type_pgp::init($gpg, $temp_dir = null, $rows = null, $cols = null) must be compatible with Horde_Form_Type_longtext::init($rows = 8, $cols = 80, $helper = []) in /usr/share/php/Horde/Form/Type.php on line 843

It seems that development of Horde has restarted, and there are some alpha
versions, mostly just fixing PHP compatibility bugs. While in general packaging
alpha versions might not be a great idea, in this case I think it might be
useful to do so, since Horde is essentially unusable in Debian 12.
