PHP Warning: Array to string conversion formatting.php on line 1096

Hello,

What I noticed was that when I go to the cutomizer in WordPress I get these php errors on my server:

PHP Warning: Array to string conversion in C:\apache24\htdocs\mydomain\wp-includes\formatting.php on line 1096

Is this already known to you?
