If I understand correctly, the presence of these errors indicates invalid data in the database. This should not just be ignored. On the other hand, MediaWiki should not fatal out either. I suspect that the same error would not just occur while generating dumps, but also when trying to view the respective revision? In general, exception handling should happen as close to the UI as possible. For bulk operations like dump generation, that is of course inconvenient, since it would abort the dump. Exceptions should be caught in a way that allows dump generation to proceed, but the exception should be reported to the user somehow, both on the CLI as well as on Special:Export.
