Hi List!

Had a quick look at this, but I don't understand the dissector
packet-ber.c, so I might break more things than fix if I put a hand on it.

The bug: when loading the above file, will get a message:

Dissector bug, protocol KRB5, in packet 568: "" - "" invalid length: -1
(proto.c
:2241)

In function dissect_ber_sequence() it will call proto_tree_add_text() in
line 868, which seems to use an offset that's beyond the packets end.

Could someone with more knowledge in this dissector fix it?
