** Description changed:

  Today I wanted to upgrade the security of my SSH keys to use PBKDF.
  After struggling with ssh-agent I realised that either Gnome Keyring was
  unable to handle the new ssh key or it was a problem with ssh-agent.
  
  After troubleshooting historic bugs with ssh-agent I was unable to make
  it work. It always returned the error "Agent admitted failure to sign
  using the key on big endian machines"
  
  The problem seems to be that Gnome Keyring is unable to handle the
  complex newly encoded passphrase.
  
  Steps to reproduce:
  
  1. Create a SSH key with PBKDF
  
  ssh-keygen -b 4096 -o -a 500
  
  2. Either overwrite or create new keys with default identity id_rsa
  3. Protect it with a strong password (256-But Hex Key)
  4. Delete previous keys stored by ssh-agent
  
  ssh-add -D (for manual entries)
  ssh-add -d (for automatic entries)
  
  5. Reset ssh-agent to be extra confident that ssh-agent is not storing
  anything in memory
  
  killall ssh-agent; eval `ssh-agent`
  
  6. Add the new key
  
  ssh-add
  
+ 7. You may get an error when trying to use keys to ssh a server saying
+ "Agent admitted failure to sign using the key on big endian machines"
  
- 7. You may get an error when trying to use keys to ssh a server saying "Agent 
admitted failure to sign using the key on big endian machines"
+ Disabling ssh-agent means that I'm able to input password in console and
+ use my private key. I can then log in to my server OK. So I don't think
+ there are  problems with the generation of keys either
