Thanks for the responses. I can't use delete() because I need the keypair to still be there. Haven't tried to create a simplified script+data to reproduce this, but the problem is fully reproducible on my real script+data. Worked around it by avoiding undef values in the first place, so my problem is solved for now. Still a bit curious about the error message and why it happened though.
