What steps will reproduce the bug?

When trying to sync https://www.linkedin.com/pulse/uncertain-futures-using-chatgpt-generate-risk-fair-inputs-whitsitt/ from the Android app, or reload it in the web UI, the following error shows in the logs. This leads to a 500 page in the web UI, and prevents the Android app from syncing in either direction.

[2022-12-25 12:53:00] app.DEBUG: DownloadImages: working on image: //:0 [] []

The offending string is indeed present in the original HTML of the page, as the src of some imgs, e.g.,

I guess this Exception should be caught, and failed gracefully on, rather than let it bubble up.

SQL workaround in the meantime:

update  wallabag_entry  set content=replace(content, '//:0', 'file:///dev/null') where id=8677  ;

Another similar issue, on the same article, due to another unsupported image URI, also leading to a 500.
