Build Information:

1.2.3, without POSIX capabilities, with libpcre 7.6, with SMI 0.4.3, without
ADNS, without Lua, with GnuTLS 2.2.2, with Gcrypt 1.4.0, with MIT Kerberos,
without PortAudio, without AirPcap.

Built using gcc 4.0.1 (Apple Computer, Inc. build 5250).

When dissecting some SNMPv3 packets (with SMI enabled, if that matters), I got
the following error:

[Dissector bug, protocol SNMP: proto.c:1405: failed assertion "hfinfo->type ==
FT_BYTES"]

I will attach a sample, two-packet snippet of a conversation which exhibits the
bug (as well as the relevant MIB file).  The SNMPv3 credentials which should be
entered into Wireshark are as follows:
 - UserName: admin
 - AuthPasswd: password
 - PrivPasswd: password
 - sha1/des

Please let me know if you have any further questions or are unable to reproduce
the problem.
