I got this bug report on Ubuntu, for CUPS 2.2.7:
https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1762476
The user told that the crash happened right after boot, visible by a pop-up of Ubuntu's automatic crash reporting system.
The system attached a stack trace to the Ubuntu bug report:

This is almost certainly a dupe of Issue #5258.

Did the fix of Issue #5258 not get backported into 2.2.7? The original reporter has this problem in 2.2.7.

It did, but after looking more closely it looks like it is crashing in another spot of the background thread... Reopening...
