[Pkg-utopia-maintainers] Bug#958384: network-manager: Crash after connecting to OpenVPN

Tue Apr 21 10:34:55 BST 2020

Package: network-manager
Version: 1.23.90-1
Severity: important

Dear Maintainer,

since the last update of Network-Manager I cannot connect to my VPN
anymore.
As soon as the OpenVPN connection is established NM itself crashes with

Apr 20 14:54:45 nike.mist.a-ix.net NetworkManager[799346]: NetworkManager:ERROR:src/nm-ip6-config.c:1937:_add_route: assertion failed: (!new || _route_valid (new))
Apr 20 14:54:45 nike.mist.a-ix.net NetworkManager[799346]: Bail out! NetworkManager:ERROR:src/nm-ip6-config.c:1937:_add_route: assertion failed: (!new || _route_valid (new))

Tried it several times and it is always reproducable.

I then downgraded the package to

network-manager=1.22.10-1
libnm0=1.22.10-1
gir1.2-nm-1.0=1.22.10-1

and it was all working again.

I attached a part of the log. If you need more of it I can clean it of
personal information and attach it.
If you need any more information I'm happy to provide what I can.

Thank you for your work,
	Mirko
