Subject: Bug 793228 nzb file with empty segment lists crash pan

NZB files which have empty segment lists crash pan (up to 0.144),
for me typically at the assertion on the last line of
Parts :: set_parts (around parts.cc line 237).

The problem is that "mc.parts" is not re-initialised for the new
list of segments if the first segment is not seen, depending on
the position in the file you will either get an incompletely
constructed PartBatch used (PartBatch relies on a default
constructor so packed_mids_len doesn't get initialised) or an
old list of segments could get re-used.
