I'm not getting any debug info in Wireshark itself, but if I look into it I'll keep your comments in mind. Thanks.

The link Jaap pointed me at sounds like the most likely cause. So I guess I'll either need to update my dev version to 1.0.0 or stick with 0.99.5.

Cheers Guys

I had the same problem a few weeks ago. I had to fix several things: 

- hidden elements are deprecated and seem to be treated differently
  than with 0.99.5

- for some fields (i.e., FT_INT) combined with certain display styles
  (i.e., BASE_HEX) are invalid - however that should cause an
  assertion to fail. Do you see any debug output on the console?

I think that (in my case) the malformed packet problem was caused by
an DISSECTOR_ASSERT_NOT_REACHED macro in proto.c that was reached
because the hidden fields are now treated differently, but I am not
sure.
