I've tried to reproduce it locally, everything is fine here. Using
emacs -Q ("GNU Emacs 23.0.60.14 (i686-pc-linux-gnu, GTK+ Version
2.12.0) of 2008-02-22 on arthur"). Remote debug.log.1.gz file is
568308 bytes, 108211 lines. That is smaller than your file, but not
sooo different.

Have you checked that your local file systems are large enough to keep
the file; especially the /tmp directory? What happens if you apply
cksum on both the remote file and its local copy?

For further analysis I would need the debug buffer of Tramp. Before
you start, please perform "(setq tramp-verbose 9)". Make sure that
there are no sensitive data in the copied file; I'll read it.

Btw, does it work if you use the "scp" method instead of "ssh"?

Best regards, Michael.
