The "ftp@" part was the crucial detail that was missing from the
original report.  The bug was in ange-ftp.  It was a very old bug, but
it was exposed by fixing bug #7383 on the trunk: since now every file
is transferred in binary mode, that bug now affects many more files
than it did before.

I fixed it on the emacs-23 branch (revision 100596 there).  The
required one-line change is reproduced below, if you cannot wait for
it to be merged to the trunk.

I'm closing this bug report.

"ftp" is the default only if you don't have PuTTY installed and on

Here's the change to fix the bug:
