Here are the fixes to the other memory leaks I found. All of them is the
result of the use of pointer to pointers construct which got the coder to
shoot himself in the foot.
To clean up such constructs, deallocs in two levels is always required. A
simple 'delete [] ptr2ptr;' is not enough.
But all of you already know that and these bugs are probably cut'n'paste
related :)
