I noticed this on my local test wiki and then reproduced it in production at https://test.wikipedia.org/wiki/Special:Log . Steps to reproduce:
- A user edits
- Block that user
- Go to Special:BlockList
- Unblock the autoblock
- Go to Special:Log
It probably affects everything that shows log entries.

The invalid title is in log_namespace/log_title so is added to LinkBatch at LogPager.php:425.
