Hi Marc,
Hi Bin, Madhura found a bug: https://sourceforge.net/p/phpmyadmin/bugs/4110/
and git bisect tells me that your commit introduced it: https://github.com/phpmyadmin/phpmyadmin/commit/6bb321670bbe5f5b086c4e021320...
but from my testing, it is working for me. the Totals for database statistics is a valid value. I will update the bug.
thanks, Bin
