Valgrind кричит о неинициализированных байтах

Valgrind выдает эту ошибку:

==11204== Syscall param write(buf) points to uninitialised byte(s)
==11204==    at 0x4109033: write (in /lib/libc-2.13.so)
==11204==    by 0x8049654: main (mmboxman.c:289)
==11204==  Address 0xbe92f861 is on thread 1 stack
==11204==

Какая проблема? Я не могу найти, что неинициализированный байт, о котором он кричит. Вот криминальные строки кода (указанная строка 289 - это та, которая вызывает функцию lockUp):

Request request;            
Response response;              

fillRequest(&request, MANADDUSER, getpid(), argument1, NULL, NULL, 0, 0);
lockUp(&request, &response, NULL);

Здесь описание прототипа функций и структур:

void fillRequest(Request *request, char code, pid_t pid, char *name1, char *name2, char   *object, int id, size_t size)
{
    int k;

    request->code = code;
    request->pid = getpid();

    if(name1)    for(k=0; k<strlen(name1)+1; k++)   request->name1[k] = name1[k];
    else         request->name1[0] = '\0';

    if(name2)    for(k=0; k<strlen(name2)+1; k++)   request->name2[k] = name2[k];
    else         request->name2[0] = '\0';  

    if(object)   for(k=0; k<strlen(name2)+1; k++)   request->name2[k] = name2[k];
    else         request->object[0] = '\0'; 

    request->id    = id;
    request->size = size;
}

void lockUp(Request *request, Response *response, void **buffer)
{
    int fifofrom, fifoto, lock;     /* file descriptor delle fifo e del lock */

    /* locko per l'accesso alle FIFO */
    if((lock = open(LOCK, O_RDONLY)) == -1)   logMmboxman("error in opening LOCK\n", 1);

    close(fifoto);

    /* rimango in attesa della risposta da mmboxd sulla fifofrom */
    if((fifofrom = open(FIFOFROMMMBOXD, O_RDONLY)) == -1)   logMmboxman("error in opening FIFOFROM\n", 1);
    else                                                    logMmboxman("opened FIFOFROM\n", 0);

    if((read(fifofrom, response, sizeof(Response))) != sizeof(Response))   logMmboxman("error in reading FIFOFROM\n", 1);

            else                                                    logMmboxman("opened FIFOFROM again for the buffer\n", 0);

            *buffer = (void*)malloc(response->size);

            if(read(fifofrom, *buffer, response->size) != response->size)   logMmboxman("error in reading FIFOFROM again for the buffer\n", 1);
            else                                                            logMmboxman("read from FIFOFROM again for the buffer\n", 0);
