Running tshark through valgrind gave me this error:

==22743== Invalid read of size 1

==22743==    by 0x56F0550: call_dissector_work (packet.c:485)

which points to this code:

                        if (flags & (1 << 3)) {
                                /* A null terminated filename */

                                while (*c != '\0') {
                                        c++; <<<< this is line 2897
                                }

                                c++;
                        }

so it appears this is a dup of 2649.
