Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-46-generic x86_64
Distribution: Ubuntu 19.10

-- Information about the crash:
- What I was doing when the application crashed:
Launch Kubuntu, then the login screen appears, password OK, 
then the usual background appears for a while, with the arrow in the middle, I can move the arrow, there are no menus;
and then a black screen with the arrow in the center appears and stays without change. I can move the arrow.
I can open programms with alt+F2.
I have upgraded from 18.04 LTS to version 19.10 without change. I can launch Ubuntu without problem.

- Unusual behavior I noticed:
this black screen.

The crash can be reproduced every time.

Comment 3 Gesbu 2020-05-03 13:22:53 UTC 
Hello,

I effectively had two duplicated print jobs when I run lpstat -R. After 
running cancel -x -a (as suggested in comment 58) everything works fine 
again. I remember having installed a new printer (Epson ET-3750) with a 
Wi-Fi connection and having some trouble with the printing of the first 
documents.

Thanks for your help!
