Comment # 1 on bug 8222 from 
this is an "endless loop" in the dcp-etsi protocol

it's trying to reassemble fragments in dissect_pft_fec_detailed()
apparently, due to rs error correction, this protocol does not need all
fragments for the reassembly, missing fragments can be filled with 0s

the sample capture tricks the dissector into believing that we do have the
fragment for offset 262144 plus enough other fragments such that we can attempt
reassembly. the dissector now tries to insert 262144/fragment size dummy
fragments filled with 0s...

so this is not exactly an endless loop but annoying nevertheless

I comitted a fix in r47123 that stops reassembly attempts if more than 1000
consecutive fragments are missing.
