Could you, please, (setq debug-on-error t) before starting Tramp? When
the error occurs, I'ld like to see the resulting backtrace.

According to the Tramp Changelog, there was a fix on October 3rd which
*might* be related to your problem. But it's not for sure. (Your Emacs
build is dated October 1st).

Hmm. Ports shall be relevant during connection setup only. When you
open a file, they are not involved anymore I believe.

You are using Tramp 2.1 now. The codebase is seriously different.

However, there is also something strange in the traces you've sent:

> tramp_exit_status $?

Tramp believes that /home/martin/tmp/ is your temp directory on the
remote host. Tramp checks for this directory and finds out that it
doesn't exists. But then ...

> 00:22:38 tramp-send-command (6) # cp -f /home/mflack/vc/work/stable2repo 
> /home/martin/tmp/tramp.7153K4U
> 00:22:38 tramp-wait-for-regexp (6) # 
> cp: cannot create regular file `/home/martin/tmp/tramp.7153K4U': No such file 
> or directory

... Tramp seems to ignore this knowledge.

Could you, please, check what's up with /home/martin/tmp/? And I will
check how Tramp handles the temporary directory issue.

Best regards, Michael.
