Non-static method MDB2::errorMessage() should not be called statically

Just installed a fresh copy of roundcube 0.8.5 and im getting this error on the installer page step 3. Test config

Not important as everything works, just thought you'd like to know

Check DB config

I'm getting the same error on a clean install.. I changed my error_reporting statement in php.ini to the suggested settings and didn't make a difference.  What else can I try?
