Ethereal-dev: Re: [Ethereal-dev] Assert in print.c get_field_data() creating PD ML file
My only idea there is to ask if you used
tvb_set_child_real_data_tvbuff() to attach the real data tvbuff to the
real/subset chain passed to your dissector.

On what data is the tvbuff created? Is it a sub-set of a previous
tvbuff, or is it a "modification" (decompression, decryption) of
previous tvbuff data? I.e., are you using a "subset" tvbuff or a "real
data" tvbuff?
