It actually finds what it can, which is faulty because the “Fast scanner
for RFC-822 type header information” (tagfile.cc) failed to read the
stanza properly.
I added some traces to pkgTagSection::Scan(), dumping std::string(Start,Stop)
after both TrimRecord() calls, and got that:

I guess something should read a bit more to get the full stanza,
otherwise, some fields (Filename here) end up getting truncated.
Good luck fixing the scanner. :-)
