I first encountered that bug when installing Kubuntu 17.10 on my HP Zbook. I found a turnaround (see below) but the bug reappeared today after upgrading to Kubuntu 18.04.
The segfault appears in libkcupslib.so, which is in the print-manager package:
$ apt-file search libkcupslib.so
print-manager: /usr/lib/x86_64-linux-gnu/libkcupslib.so
So I removed it:
$ sudo apt-get remove print-manager
After reboot or relogging, plasma is now working.
The problem is that I can't print anymore. And if I reinstall print-manager the bug is back.
Note that I installed Kubuntu 17.10 & 18.04 on 5 machines, and the bug appears only on my HP Zbook.
