seahorse use 100% CPU after attempt to change OpenSSH Passphrase

[krom]

​Seems to be similar to bug #556349, but hidden a little deeper.

I have various OpenSSH keys credentials stored for seahorse. Those OpenSSH keys are displayes using a tabbed list view in seahorse. When double-clicking an entry, to view details (including masked / unmasked) password, then click "Change Passphrase", cancel or change changing and now the CPU Load goes to 100% upon the dialog being opened.

Reproduce:

1) Run seahorse with some OpenSSH keys.
2) Click "OpenSSH keys" on the left panel.
3) Double-click on some of you SSH keys.
4) Click "Change Passphrase".
5) Click "Cancel". (or really change pass, works for me too)

Observe CPU Consumption.
