esp-idf: [TW#19695] Smart config example fails to connect to wlan

The smart_config example (using esp-idf commit 8478823) runs and install fine. The correct SSID and PASSWORD is received, but after that connecting to wlan seems to fail with output below. I tried it on two ESP32 modules, both have same result. (The simple_wifi example works fine on both modules.)
