[Pkg-utopia-maintainers] Bug#779604: network-manager: NetworkManager crashes on modem hangup

[Nils Dagsson Moskopp]

Package: network-manager
Version: 0.9.10.0-6
Severity: important

Dear Maintainer,

NetworkManager seems to randomly crash since a recent upgrade.
I have found in syslog something that might lead to a solution:
