To reproduce:

  • Go into (new) Network preflet
  • Choose IPv6 tab
  • Press Apply

comment:2 by jackburton, 5 years ago

It seems there are still locking problem in the network stack. Could be related to #9377 ? By the way there is still a pending patch of mine in that ticket (which could help, or maybe not). Someone should review it.

comment:4 by pulkomandy, 5 years ago

I can't reproduce this with the given instructions. Does it need something particular in the network setup (eg. do you have a DHCP server providing ipv6 leases?)

comment:5 by pulkomandy, 4 years ago

I think jackburton applied his patch now. Does it help?

comment:6 by kallisti5, 4 years ago

Resolution: fixed
Status: newclosed

no longer crashes as of hrev50047. Setting the IPv6 address static or disabled results in an instant transition to "automatic" and settings are lost... but at least it doesn't crash :-).

There are several core IPv6 bugs still (#12245, #12246, #12247) but this crash now solved :-)

Note: See TracTickets for help on using tickets.
