[Pkg-utopia-maintainers] Bug#911591: network-manager: Segfault at service startup on i386

Mon Oct 22 11:13:26 BST 2018

Package: network-manager
Version: 1.14.2-2
Severity: normal

This bug report was saved with reportbug but sent with the gmail web
interface: I hope it looks good.

After upgrading from 1.12.4-1 to 1.14.2-2 the service segfaults and
doesn't start anymore. Rebooting doesn't help.

But i've successfully upgraded NetworkManager to the same version on
another Debian Sid machine: apart the different hardware, I think the
real difference is the architecture:
- i386 (here): fail
- amd64: ok

Journalctl report this:

After downgrading network-manager, libnm0 and gir1.2-nm-1.0 to
1.12.4-1 using snapshot.debian.org, now it starts again.
