No, it seems to be different to me. In my case the chunk encoding is
removed properly, the retrieved .deb file has the correct size, but
the contents is garbled.

But I found the problem described in bug 152711 that was referenced
from 274978. None of the fixes proposed there obviously has been
applied to the current version of apt in 'testing', though the last
message claims to have fixed this bug in apt-0.5.25 (current is 0.5.27).

And the routine CirclBuf::WriteTillEl() in http.cc from the apt source
package 0.5.27 is definitely still buggy and will eat up a <CR> that
happens to appear right at the beginning of a data chunk.
