Something has broken Chromium

[Gene Heskett]

Chromium worked yesterday morning, but now launching from the menu times 
out, calling up a konsole says something on the system has changed.

From that konsole screen: (word wrap turned off)
gene at coyote:~$ /usr/bin/chromium-browser
[2651:2670:0408/214523:ERROR:object_proxy.cc(624)] Failed to get name owner. Got org.freedesktop.DBus.Error.NameHasNoOwner: Could not get owner of name 'org.chromium.Mtpd': no

Anybody that can help?

Thanks all.

Cheers, Gene
