Actually, that error should only happen when you try to change your *own* name. The fact that the name seems to change while it doesn't is an unrelated bug that should be easy to fix.

I'd need deeper debugging to understand what's going on. Could you install the package for your architecture from:
http://ddebs.ubuntu.com/pool/main/s/system-tools-backends/

and then run
sudo killall system-tools-backends
sudo gdb /usr/sbin/system-tools-backends
break dispatcher.c:547

then reproduce the problem, and when gdb stops, type
print (message_uid == uid)
print message_uid
print uid
and print the result here.

In short, it seems that we're not detecting the right UID for your user, which means you're not allowed to change your own information. Thanks for your help!
