text: In networks that don't have a DHCP server configured, ipv4 address
  allocation fails and the ipv4 structure doesn't get populated. When
  the GUI is trying to read the ipv4_config.method field to see whether
  it contains "dhcp" string, a segmentation fault is generated.
  
  Ethernet manual configuration behavior remains unchanged after this fix.
