Temple of power + chandra's emblem cause a game error

[copperfield42]

I have [[Ojer Axonil, Deepest Might]] in its back side (Temple of power) and the emblem from [[Chandra, Torch of Defiance]], and when trying to resolve the emblem trigger I got this error:

Game exception occurred:

(I specifically destroy Ojer to reproduce this error that I got in a previous game but forgot to screenshot)

If a red source you control would deal an amount of noncombat damage less than Ojer Axonil's power to an opponent, that source deals damage equal to Ojer Axonil's power instead.
When Ojer Axonil dies, return it to the battlefield tapped and transformed under its owner's control.
