Description Christian Lohmaier 2018-02-06 01:42:08 CET

Description of problem:
Try to use bluetooth tethering by connecting to your phone (I use corresponding menu from gnome-menu, but any other networkmanager tool gives same result):

NetworkManager[883]: <info>  [1517855956.3374] dhcp4 (bnep0): activation: beginning transaction (timeou
NetworkManager[883]: ((src/platform/nm-platform.c:2650)): assertion '<dropped>' failed
NetworkManager[883]: g_array_sort_with_data: assertion 'array != NULL' failed
kernel: NetworkManager[883]: segfault at 8 ip 00000000004a5ff2 sp 00007ffd219ae5e0 error 4 in NetworkMa


As a result of networkmanager crash, dhcp is not triggered (can fix that by running "dhclient bnep0"), and NM fails to acknowledge the device afterwards:
when trying to setup VPN connection it fails with 

result="fail" reason="Could not find source connection."

Version-Release number of selected component (if applicable):
1.8.0

How reproducible:
always

Steps to Reproduce:
1. enable bluetooth tethering on your mobile
2. try to enable the bt internet connection via networkmanager
3. fails to init properly, no internet connection

(can get internet by manually running dhclient as outlined above, but even after that enabling VPN is not possible using networkmanager)

I'll check this one. I think I'm going to update nm to the latest stable in 1.8 series.

Pushed networkmanager 1.8.6 which should fix the issue and includes fixes also for bug 21685. Please test new nm from core/updates_testing.

 Track NetworkManager update in a single update bug to not confuse QA / testers...
