Warning array_merge(): Argument #2 is not an array

Hi,
I just tried installing EasyBlog Professional Version 3.9.22134 on Joomla! 3.4.0 and received the following warning:

Warning: array_merge(): Argument #2 is not an array in /home/cloud/public_html/libraries/vendor/joomla/registry/src/Format/Ini.php on line 57

The system environment is:
Debian 3.2.54-2 x86_64
PHP Version 5.4.36-0
Apache/2.2.22
MySQL 5.5.41

should I worry about this warning, is it something that will be fixed in the future etc?
Please advise,

Thank you
Tom D.
