 Tramp with ssh not working with openssh 6.7 while worked with 6.6
Date: Tue, 27 Jan 2015 17:41:26 +0300

I've recently upgraded openssh to 6.7 on MacOS X (from MacPorts) and ssh
in Tramp stopped working.  Logs are below.  Activating openssh 6.6
brings back the working state.

The file being opened is /ssh:root@<myhost>:/opt/ as can be seen in the
logs.
