On attempt to start session either via TDM greeter or startx, popup message 
reports:

"There was an error setting up inter-process communications for TDE. The 
message returned by the system was:
Could not read network connection list.
/home/username/.DCOPserver_hostname_0
Please check that the "dcopserver" program is running!"

Then on dismissing that popup, another reports:

"Could not start tdeinit. Check your installation."

So, check how? What's supposed to start dcopserver? Is the "cannot open" 
message in .xsession-errors saying that some dependency is broken? I see 
mention of libbfd there, but 2.26.1-system.so (not libbfd-2.26-system.so) 
does exist in /usr/lib/x86_64-linux-gnu/. Do others have 14.0.3 running OK on 
16.04?
