While trying to track down a problem I'm having I tried loading the file
"tcp-wireshark-file1.trace" from the SampleCaptures page.  That page says the
file's a libpcap file but my 'file' utility says it's a JPEG (go figure).

Anyway, loading it results in almost no (useful) dissection and an assertion:

17:53:26          Warn Dissector bug, protocol JFIF (JPEG) image, in packet 2:
../../epan/tvbuff.c:1550: failed assertion "DISSECTOR_ASSERT_NOT_REACHED"

The JPEG may be messed up because I couldn't open it with one image viewer
(though I could with another).

(I don't have time to look at this right now which is why I'm filing the bug.)
