The error was detected while upgrading from D6 to D7 and executing the update htmlpurifier_update_7000. There is an error on htmlpurifier_update_7000 function in htmlpurifier.install. In line 276 its used a mysql specific function to get the row count:

    if (mysql_num_rows($query) == 0) {
        db_drop_table($d6_table);
    }

The solution is to use a equivalent DB api function.

The patch also fixes my error on update 7000 when upgrading from D6:

mysql_num_rows() expects parameter 1 to be resource, object given htmlpurifier.install:278

But it's been three years since the last release so the bug is still in there. Any plans for a new release?
