[Pkg-utopia-maintainers] Bug#864071: SIGSEGV when connecting to bluetooth network

[chrysn]

Package: network-manager
Version: 1.8.0-2
Severity: normal

When I connect to the Bluetooth connection to an Android cellphone I
paired via bluetooth using blueman, network-manager segfaults.
Backtrace:

Based on the trace, I set IPv6 on that interface to "ignore"; the link
then works as expected.

Please let me know if and which other debug information you might need.
