I've just started using SharePoint Online (part of Office 365).
I'm creating an Intranet using Publishing Pages. Most of the pages are using the Welcome Links page layout.
On some of the pages, I wanted to add a List View Web Part (supplied with SharePoint).
I could add these to the page. However, when I selected "Edit Web Part" I saw the following SharePoint error:
No item exists at https://sitename/OpsManagement/Pages/default.aspx?Filter=1&FilterOnly=1&List={7B611D12-3559-4F60-9B6B-265CA420177B}. It may have been deleted or renamed by another user.
After some trial-and-error, I noticed that this issue does not occur if the page is using the Blank Web Part page layout. Note that this page layout does not render the Publishing Image field.
My conclusion is that the issue is caused by a conflict between the Publishing Image field (rendered by the Welcome Links layout) and the List View Web Part.
(Maybe this is due to the new image rendition functionality?)
I've raised a ticket with Microsoft support and will report back any findings.

Microsoft accepts that this is a bug and is working on a fix. No indication of when this will be resolved. I'll provide another update when it is.
Update 27/06/2014
Just finished a call with Microsoft. It would appear the problem has now been fixed as part of a different ticket.
