commit e702c6508e9b2e8082d99683ba933e9679608251
Author: Albert Astals Cid <aacid@kde.org>

Move the const_cast from assignment to free
The problem is that some of the times the pointers hold values
to const tables and some others hold values to dynamic memory.
Instead of const_casting the const tables when needed and holding a non
const pointer, we hold a const pointer and only const cast on free if
needed
