Bug 697868 – net-print/cups-2.3.0 - crash in cgiGetArray at var.c:173

• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description Martin Mokrejš 2019-10-16 15:39:59 UTC]

I am still having some issues with the recent cups+cups-filters combo. For example, I cannot list existing jobs and cancel them. There is just no button for that. The only way to cancel all jobs is through http://127.0.0.1:631/admin -> Jobs ->  Manage jobs. I think there was always a way to cancel an individual job listed in in those pending currently.

I see some crashes in /var/dump so I assume they are related to this broken functionality:
