x2go client hangs

[pgera]

This may be an X2Go bug, but reporting it here first if this is a known issue. x2go client has a checkbox for "try ssh-agent or default ssh key". If that is checked, it first prompts for a passphrase to decrypt the key. Upon entering the passphrase, it hangs.

It may be an X2Go bug, but I'm suspecting it's simply that simple-tpm-pk11 doesn't yet implement one of the PKCS#11 calls that X2Go happens to make.

I've implemented them on a when-needed basis.

I don't see myself having time to look into this in the foreseeable future, but would prioritize and accept pull requests.
