Ikey Doherty 605c7ee87b Fix compiler warnings with uninitialised cleanup pointers
This change fixes GCC compiler warnings where a cleanup function was
specified on an uninitialised pointer, which in the view of GCC could
result in an errornous free of uninitialised memory, if the functions
that initialise them do not return NULL.
