[klejeune]

Describe the bug

When trying to send ETH on Ethereum mainnet, the extension crashes.

Expected behavior

The extension shouldn't crash and the send should work

Steps to reproduce

1. Try to send ETH to another account
2. Confirm
3. See the app crash

The issue doesn't always reproduce, but it did 4 out of 7 tries for me.
Also reproduced with sending mUSD on Ethereum mainnet.
