One of the sysadmins at $job made me chant the following 10 times when i mentioned a bug like this
Cron, at and batch run in a heavily cut down environment
... and would later ask me stuff like 'what is special about cron, at and batch?' or 'when might your script be running in a heavily cut down environment?'
this went on for about a week, although i'm not sure what his point was...

nothing like public humiliation to prevent repeating bad behaviour.

Aren't RSA and DSA keys generally tied to a specific user account (and, in
some cases, also a specific hostname)? If you're running out of cron,
isn't it possible that you're running as a different user (e.g., root),
and that your RSA and DSA keys are not valid for the other user account,
only for yours?
Sanity? Oh, yeah, I've got all kinds of sanity. In fact, I've developed whole new kinds of sanity. You can just call me "Mister Sanity". Why, I've got so much sanity it's driving me crazy.

Well, the script is executed as the root user using roots rsa/dsa keys so I cant see that would be the problem. After turning on debugging for SSH in the script I found out that the passphrase authentication for the keys dont work under batchmode. And here is where I am at the moment, stuck :-)

Net::SSH::Perl always reads passwords and passphrases
from the terminal (the tty). Passphrases therefore don't work in batch mode, by design.
See Is Net::SSH::Perl broken for login via explicit user/password? for more info.
