Description Thomas Haller 2016-09-16 08:06:45 EDT

+++ This bug was initially created as a clone of Bug #1376446 +++

Description of problem:
When I try to call Reapply of a bond slave ethernet connection NetworkManager crashes with a segfault (based on log in journalctl). This is using the interface exposed over D-Bus, using python.

Version-Release number of selected component (if applicable):
NetworkManager-1.4.0-4.fc26.x86_64

How reproducible:
always

Steps to Reproduce:
1. add bond connection
2. add slave ethernet connection
3. activate bond connection
4. activate slave connection
5. call Reapply on the device that the slave connection is applied on

Actual results:
Crash with segfault.

Expected results:
Nothing happens. Maybe an error of an invalid or "empty" operation.


Additional info:
python reproducer attached, example use:
./nm_reproducer.py ens9 52:54:00:38:c4:24



----

a crash, with a trivial fix.
