Problem/Motivation
Once upon a time aggregator did its own RSS parsing.
During the D8 cycle we moved to using a third-party parsing library provided by Zend.
The error is no longer occurring but it is not know if we have test coverage (either in core, or in Zend) for invalid descriptions.
Proposed resolution
Review test coverage in core and Zend and ascertain if there is handling for malformed RSS descriptions.
If so, we can mark this closed (duplicate) and link to the issue where we added Zend's feed parser
If not, we can revive the test coverage here.
Remaining tasks
Review test coverage in core and zend to ascertain if mangled descriptions are handled.
If not, revive the test coverage here.
User interface changes
API changes
Data model changes
Release notes snippet
This error appears if a feed's channel has no description element. Attached patch fixes the error.
