I had almost if not identical backtrace. Pretty sure this is a dup of bug #88256, which is now fixed in adept 2.1.2ubuntu19 .
So I suppose apt-get upgrade should get you out of there, but I am not too sure about your 'packages have been kept back'. -- adept crashes at startup after an execution of apt-get upgrade https://launchpad.net/bugs/88928 -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
