Just saw this on their status page:
Update - Withdrawals are now enabled. We are aware of a rare issue preventing some new withdrawal addresses from being confirmed. Please try another address if this happens. Also, if you held bitcoin on your Kraken account at Bitcoin block #472889, you have been credited with your Stellar lumen (XLM) from the last airdrop. Note: the new trading interface still uses the old STR ticker (https://trade.kraken.com/kraken/strbtc)

If you had bitcoins on Kraken around June 26, 2017 you got some free Lumens. Check your Kraken account!
