Hi, as per , I'd like to ask you to switch to building with Python 3. AFAIK gnome-abrt is ported upstream, so it should be a simple matter of changing the downstream packaging.
Oh, and the missing reference  is: https://fedoraproject.org/wiki/Changes/Python_3_Migration_Improvements
As of 1.1.0-1 gnome-abrt is built with python3.
This bug can be closed.
Thank you for the reminder.
