Doesn't switch to IPv4 route when IPv6 is broken
Was alerted to a ipv6 configuration error today when evolution would not load any of my accounts. Accidentially enabled router advertisements on a device that I shouldnt have. Anyway, evolution repeatedly times out, and makes no effort to switch to ipv4. The lack of verbosity of the error and the mention of a "access token" made me think I had a keyring problem.
Maybe this can help.
