Thank you for taking the time to report this bug and helping to make
Ubuntu better.

I cannot reproduce this. My log is below. Could this be a
misconfiguration on your system? For example, your lines "debug1:
key_load_private_cert: No such file or directory" suggest to me that you
are running a non-default configuration.

Since it seems likely to me that this is a local configuration problem,
rather than a bug in Ubuntu, I'm marking this bug as Incomplete.

If indeed this is a local configuration problem, you can find pointers
to get help for this sort of problem here:
http://www.ubuntu.com/support/community

Or if you believe that this is really a bug, then you may find it
helpful to read "How to report bugs effectively"
http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful
if you would then provide a more complete description of the problem,
explain why you believe this is a bug in Ubuntu rather than a problem
specific to your system, and then change the bug status back to New.

My failure to reproduce:
