This bug has been created based on an anonymous crash report requested by the package maintainer.
Report URL: https://faf.lab.eng.brq.redhat.com/faf/reports/bthash/c91a4ab31439b13c8686d8622306ee30b5165255/
Thanks for a bug report. From a different FAF report, it fails with this message:
e-test-server-utils-FATAL-ERROR: Unable to create the test calendar: Unable
to connect to "Unnamed": Backend factory for source "eds-source-O4H2OZ" and
extension "Calendar" cannot be found
It can be that the client (test) side called to create the source, then it received it's created before the factory, and when the test asked to create also the EClient instance the factory side still didn't know about the source and failed the call with this error message. The 3.28.5 doesn't differentiate between the ESource not found and the backend not found states.
This is addressed by this change:
I updated the patch for this bug with these two upstream changes, which are related:
