PermissionError: [Errno 13] Permission denied when capturing executable path

My OS: Ubuntu 18.04.4 LTS (GNU/Linux 5.3.7-x86_64-linode130 x86_64)

I've noticed that apport (version 2.20.9-0ubuntu7.9) is reporting a "permission denied" error when processing PHP-FPM 7.2 crashes, which is preventing the production of crash reports. This is what I see in /var/log/apport.log:

/proc/16310/exe looks like this:

lrwxrwxrwx 1 root root 0 Feb 12 14:04 /proc/16310/exe -> /usr/sbin/php-fpm7.2

/usr/sbin/php-fpm7.2 looks like this:
