Strange (to me) error message in KMail

Debian Wheezy 7.8 Trinity R14.0.1 KMail 1.9.10 It is a new installation of both Trinity and KMail on a new computer. Initially it worked fine and a pile of new messages downloaded. Now it won't download and I get the error message: 'could not connect to host localhost' I have run it from a terminal, and I get: john@Harrier:~$ kmail [TDE NM Backend ERROR] [/tmp/buildd/tdelibs-trinity-14.0.1/tdecore/tdehw/networkbackends/network-manager/network-manager.cpp:1224] org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.NetworkManager was not provided by any .service files [TDE NM Backend ERROR] [/tmp/buildd/tdelibs-trinity-14.0.1/tdecore/tdehw/networkbackends/network-manager/network-manager.cpp:1224] org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.NetworkManager was not provided by any .service files [TDE NM Backend ERROR] [/tmp/buildd/tdelibs-trinity-14.0.1/tdecore/tdehw/networkbackends/network-manager/network-manager.cpp:1803] org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.NetworkManager was not provided by any .service files kmail: WARNING: Autosave directory /home/john/.trinity/share/apps/kmail/autosave/cur not found! john@Harrier:~$ WeaverThreadLogger: thread (ID: 1) suspended.

Weaver dtor: done ^C john@Harrier:~$ When I shut down KMail, the Konsole hung at <Weaver dtor: done>. I then did ^C to shut it down in the Konsole and shut the Konsole. What do I do to get KMail working, or do I have to put this client back on Icedove and Mbox. :-( Thanks, Lisi
