Bug ID: 395115
Summary: print-manager v18.04.1 interacts badly with recent
cups v2.2.8, numerous errors leading to high system
load
Product: print-manager
Version: 18.04
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: dantt...@gmail.com
Reporter: tatkinson...@googlemail.com
Target Milestone: ---
First bug report to KDE.
If I've missed out any detail, please let me know.
Originally posted downstream on the Gentoo bug-tracker.

I've been asked to raise the issue upstream.
After a recent update from cups v2.2.7 to cups v2.2.8, I'm seeing lots of
errors being thrown by libkcups
The following 3 error messages are being repeated over and over in the journal
(several times per second)
Jun 07 12:44:15 tony-workstation plasmashell[679]: libkcups: 3 "LaserJet8150"
Jun 07 12:44:15 tony-workstation plasmashell[679]: libkcups: CUPS-Get-Printers
last error: 0 successful-ok
Jun 07 12:44:15 tony-workstation plasmashell[679]: libkcups: "040B localhost
\"requesting-user-name\" attribute with bad value."
This is causing system load to rise significantly
top shows libkcups and plasmashell processes at 70-80% CPU usage
Tried reinstalling print-manager, but this made no difference.
Downgrading from cups v2.2.8 to cups v2.2.7 fixes issue.
