[Pkg-utopia-maintainers] Bug#1006622: network-manager: Upgrade from 1.34.0-2 to any higher version breaks IPv6 config on mobile broadband

[Bjoern Buerger]

Package: network-manager
Version: 1.36.0-2
Severity: important
Tags: ipv6

Dear Maintainer,


after upgrading network-manager from version 1.34.0-2 to 1.35.91-1 or higher,
NetworkManager fails to set the IPv6 addresses, received via mobile boradband
connection.

* Downgrading to 1.34.0-2 immediately fixes the problem.
* All later Versions, starting with 1.35.91-1 are affected
