Not a bug preg_replace() Error in Debug Mode with PHP 5.5.15

[ibnesayeed]

I have upgraded my PHP version from ppandrej/php5 and it was upgraded to 5.5.15 (released today). As a consequence no I am seeing an ugly error in my ACP when I enable debug mode for development. I see a bunch of repeated errors saying:

preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in library/Zend/Filter/PregReplace.php, line 171

Thanks!

With your hint, I was able to figure out that the add-on Profile Completion Steps from @Robbo is causing this issue on our board.
