>>> This is incorrect, as I've just had it happen to me (again) and I'm using Eoan. Although if that actually meant the problem wasn't with plasma-workspace but rather with print-manager then I disagree. Clearly plasma-workspace has the ability to crash when presented with incorrect data. That itself is a bug! Applications should validate their input and handle errors appropriately. A crash is not an appropriate handling.

The bug is still present in Kubuntu 19.10 (KDE Plasma 5.16.5), and it appeared two years ago in Kubuntu 17.10. I have reinstalled the package print-manager on my notebook to install a new printer, but I was obliged to remove print-manager after plasma crashed when trying to print as the Wi-Fi was off. Note that without the print-manager, I can not add printers but I can still print on already installed printers. So you can install print- manager each time you need to manage a new printer then uninstall the package. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to plasma-workspace in Ubuntu. https://bugs.launchpad.net/bugs/1770044 Title: plasmashell crashes on login - so I can't use my desktop system.

Another +1 In my case, plasmashell started crashing like this after I had some problems with printing a document two days back. When I started the PC today (Kubuntu 18.04), plasmashell would keep crashing with the error messages outlined above. After reading this bug report, I did some digging and found the following: - One of the attempts of printing the document apparently resulted in a "stuck" print job in CUPS - That job was listed twice with the same ID - I could cancel one of them, but not the other one, as it had the same ID - After manually removing the stuck job from /var/spool/cups and rebooting the PC, everything worked again - Strangely enough, one of the two printers I had previously configured has now vanished completely from CUPS So, the root cause seems to lie in CUPS rather than KDE, but I find it extremely puzzling that an error in CUPS keeps KDE from starting properly - this seems to be a bug in itself. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to plasma-workspace in Ubuntu. https://bugs.launchpad.net/bugs/1770044 Title: plasmashell crashes on login - so I can't use my desktop system.

Btw. I was shocked that a bug in a component could bring down the whole plasma shell. Where is the design goal of decoupling of components? I mean, I love KDE, but KDEs quality seems to be dependent on every little app running there? Oh my goodness I would have expected a list of components with its status.

Exactly the same issue. Plasmashell segfault with "error 4 in libkcupslib.so". Black screen after login, all hot keys work, ALT+F2 works, but no desktop GUI.

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. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to plasma-workspace in Ubuntu. https://bugs.launchpad.net/bugs/1770044 Title: plasmashell crashes on login - so I can't use my desktop system.
