Fatal php Error with v2.12.0

[gene-git]

No login screen is presented - instead there is the 3 dot animation.
php has open_basedir in effect and /usr/bin is not in open_basedir.

I checked the server log and saw this - perhaps its relevant:

"PHP message: PHP Fatal error: Uncaught ArggumentCountError: Too few arguments to function SnappyMail\Log::warning(), 1 passed in /usr/share/webapps/snappymail/snappymail/v/2.12.0/app/libraries/RainLoop/Utils.php on line 230 and exactly 2 expected in /usr/share/webapps/snappymail/snappymail/v/2.12.0/app/libraries/snappymail/log.php:18

Thank you - confirm 2.12.1 works well.
