Possible regression when declaring a SequentialRNN

[tacchinotacchi]

I'm running this code

import fastai2.text.models as models

config = models.awd_lstm_clas_config.copy()
update = {
    "emb_sz": 300,
    "n_layers": 1,
    "bidir": True,
}
config.update(update)
model = models.get_text_classifier(models.AWD_LSTM, len(vocab), 2, config=config, lin_ftrs=[400])

It works fine at commit https://github.com/fastai/fastai_dev/commit/03e59c4e29e687adc29ae8619d59ea96e8f9fde7, but I get this error on master:

I'm getting this error while in models.get_text_classifier:

EDIT: my bad, I was pulling from my own fork instead of this repo and I missed the fix
