Change Details

1. Open [wikidata:Special:SimulateTwoColEditConflict](https://www.wikidata.org/wiki/Special:SimulateTwoColEditConflict). 2. Enter the title of a Wikibase entity page, e. g. `Q42` or `Property:P31` and submit the form. You will see an editor for wikitext, filled with the internal JSON serialization of the entity. 3. Make some edits to the “wikitext” (it doesn’t seem to matter if they make the JSON invalid or not) and submit the form. You will be redirected to an “internal error” page for a “Fatal exception of type "MWException"”. This should probably be prevented at step 2 – the form should reject titles of pages whose content model isn’t wikitext.
