Repro: 1. Create a claim on Wikidata. 2. Add reference to the claim with P14 = qqq, the system accepts it 3. Edit the main snak of the claim. It rejects my edit with "invalid value qqq" info.
I can reproduce this. It does not happen when adding a regular statement. It does happen when adding a source.

This has been fixed along the way with another patch, not the one mentioned in here. I verified that this bug is also fixed on wikidata.org already, so I'm closing it. However the patch mentioned here adds an additional test case which is also related to this issue.
