I used a breakpoint in flNotDir to detect when said udeb was being
handled. Caller was pkgAcqArchive::Done(), which extracts the filename
from the Message it receives:
| // Grab the output filename
| string FileName = LookupTag(Message,"Filename");
Showing all of Message (using gdb's “set print elements 0”):
| (gdb) p Message

So it appears the message is corrupted?
Now looking into the http method (ISTR ftp led to the same results),
adding a trivial clog call in there, I'm getting:
| Filename in http method:
/home/kibi/debian-installer/installer/build/apt.udeb/cache/archives/partial/c
so it was actually set way before that, as expected DestFile.
Trying to apt-get install --print-uris, that's indeed sufficient
to exhibit the issue, no need to download/clean/playagain.
Since Owner->DestFile is used both for creating a Message and for
printing URIs, I suspect that's the one going bad. Looking at
apt-private/private-install.cc's InstallPackages(), it appears
the Fetcher is created by the PackageManager, and one then gets the
files out of there. I suspect this is what wants getting looked at.
As for reproducing the issue:

| cd foo/build
| export DEB_HOST_ARCH=$(dpkg-architecture -qDEB_HOST_ARCH)

(I suspect one can truncate the package list some more, but that's
for another day; if you're on another arch, try this command
instead, without the export: make rebuild_netboot)
