Yes, this seems to work when I retry it, as well as manually.

There is also later an issue with terminating forwarding connections, 
but I recall you debugged this already 6-12 months ago (then the 
system was RHL73 though) and couldn't reproduce it.  So this certainly 
shouldn't be a recent problem.  With tracing enabled, the output is:

testing ssh protocol 1 socks version 4 host localhost
