Dear Maintainer,

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

Dear Maintainer,

this is becoming annoying. I now do “sudo service network-manager force-reload”
multiple times every day. From my syslog it seems network-manager always says:

I do not know what servicehelper is and could not find such a file or package.
