If this is the fix, you're running badly outdated packages. This fix  
was already released in December last year as part of Horde_Text_Filter:

------
v2.3.6
------

[jan] Fix regular expression error with PHP 7.3 (Remi Collet
       <remi at remirepo.net>, PR 1).

Before asking for help, make sure you're running the latest packages  
available from the PEAR channel at minimum.
