Description Simeon Andreev 2020-08-06 08:17:43 UTC

In our Eclipse-based application we see a ton of prints on standard error: gtk_box_gadget_distribute: assertion 'size >= 0' failed in GtkScrollbar

See Eclipse bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=538000

We've opened an issue in the GTK+ issue tracker with a GTK3-only reproducer: https://gitlab.gnome.org/GNOME/gtk/-/issues/210

The GTK+ issue has been open for 2 years without a fix, a patch suggestion was made 3 months ago.

The standard error is flooded and made useless by this error. Debugging Eclipse is also impeded, since the standard error is mixed with the error log output, making it hard to find actually useful output. In our product we had to redirect the error stream to prevent the user from seeing the unexpected GTK+ errors.

Where are you experiencing the behavior? What environment?
RHEL 7.4 with GTK3 version:

gtk3-3.22.30-3.el7.x86_64

We would like a fix in GTK3.

Red Hat Enterprise Linux 7 shipped it's final minor release on September 29th, 2020. 7.9 was the last minor releases scheduled for RHEL 7.
From intial triage it does not appear the remaining Bugzillas meet the inclusion criteria for Maintenance Phase 2 and will now be closed. 

From the RHEL life cycle page:
https://access.redhat.com/support/policy/updates/errata#Maintenance_Support_2_Phase
"During Maintenance Support 2 Phase for Red Hat Enterprise Linux version 7,Red Hat defined Critical and Important impact Security Advisories (RHSAs) and selected (at Red Hat discretion) Urgent Priority Bug Fix Advisories (RHBAs) may be released as they become available."

If this BZ was closed in error and meets the above criteria please re-open it flag for 7.9.z, provide suitable business and technical justifications, and follow the process for Accelerated Fixes:
https://source.redhat.com/groups/public/pnt-cxno/pnt_customer_experience_and_operations_wiki/support_delivery_accelerated_fix_release_handbook  

Feature Requests can re-opened and moved to RHEL 8 if the desired functionality is not already present in the product. 

Please reach out to the applicable Product Experience Engineer[0] if you have any questions or concerns.
