Status changed to 'Confirmed' because the bug affects multiple users.

e.u.c report https://errors.ubuntu.com/problem/053d4e626c72706a78ba600b3a7473740e902a66

[Sebastien Bacher (seb128)]

Looks similar to https://bugzilla.gnome.org/show_bug.cgi?id=786015 which is a segfault when n-m is restarted

[Sebastien Bacher (seb128)]

Did you restart n-m before getting the issue?

this also affects Bionic Beaver Development branch
