Also, the bug reporter indicated:
Unhandled exception ("proto.c:6698: failed assertion
"DISSECTOR_ASSERT_NOT_REACHED"", group=1, code=4)
... so while it was a guess, it was an educated guess, and it really seemed to
me that this was the cause.

It was a guess. The attachment in the bug report, namely "wint168.txt", only
revealed the following::
This application has requested the Runtime to terminate it in an
unusual way.
Please contact the application's support team for more information.
I didn't see anything wrong with the "wlan_mgt.fixed.capabilities.dsss_ofdm"
field, which was the one in which the above message appeared, so I went looking
for nearby fields for potential problems, and that's when I noticed that
hf_ieee80211_tag_supp_rates had "FT_UINT8, BASE_NONE", and the display filter
for that field is "wlan_mgt.supported_rates", which is the last thing printed
in the wint168.txt file, so I figured that was most likely the problem.

The code in epan/proto.c seems to indicate that using BASE_NONE with
FT_*INT* types should be OK when there the strings converter is supplied:

Where was it crashing (er, excepting out)? (There's no sample PCAP file
in that bug.)
