Trouble creating logerrit account

I've just tried to set this up. Looks my my RSA keygen is screwed, but I
don't know why. The trace from ssh -vvvv logerrit follows:

anthony@ashdown ~/gitstuff/loffice $

It's complaining "incorrect RSA1 identifier", but I generated the key
pair as per instructions -

ssh-keygen -t rsa -C "your_email@example.com"

The header of my private key starts

-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: AES-128-CBC,15DE1487A8D84D685BB525958FCEADC3


Obviously I used my email address - only thing is I did not use my gmail
address I logged in with, I used the email address I want to use (and I
didn't quote it). Could that possibly be anything to do with it -
although I don't think that error makes sense for that...

Cheers,
Wol
