Network Manager can't connect to hidden wireless networks

Binary package hint: network-manager

After the 13th of September updates I can't connect anymore to my university wireless network using network manager. I can connect without any problem ti unprotected or WEP protected networks.
The university network is WPA2 EAP-TLS protected. I can however connect manually using wpa_supplicant with the following wpa_supplicant.conf file:

network={
      ssid="unimib"
      scan_ssid=1
      key_mgmt=WPA-EAP
      pairwise=CCMP TKIP
      group=CCMP TKIP
      eap=TLS
      <email address hidden>"
      ca_cert="ca.pem"
      client_cert="xxxxxxxxxxxx.pem"
      private_key="xxxxxxxxxxxxxxxxxxx.key"
      private_key_passwd="xxxxxxxxxxxxxxxxxxxxxxx"
}

I can also connect using wicd.

This is the result of running NetworkManager --no-daemon:
