Syslog-Ng fails after 2.5.2 update due to tls not found

[Juve]

I upgraded a 2.5.1 system runing syslog-ng with tls sources ( tls() ).
syslog-ng service won't start giving this error:

Syslog-ng syntax test failed: Error parsing source statement, source plugin tls not found in /usr/local/etc/syslog-ng.conf

I tried doing an upgrade on another box and the resulst is the same. syslog-ng won't start with the same error message.

I did upgrade the package today and now everything work !
Thank you
