Given that I have edited an article
And I have used VisualEditor
When I try to save
Then I expect the page to be saved
And that I will be returned to the new version
What happen is that I /sometimes/ will stay on the edited page, and get a new empty save dialog.
One page where this happen is no:Vassfaret
There is an error report in Firebug. This is from editing Vassfaret with VisualEditor and debug=true
TypeError: title.getExtension(...) is null https://no.wikipedia.org/w/extensions/MultimediaViewer/resources/mmv/mmv.bootstrap.js?66f09 Line 183
Note that this interferes with the editors on nowiki, but not in a destructive manner. It is only annoying. It is not clear whether the bug is in VisualEditor and gets reported in MediaViewer, or if it is MediaViewer that interfers with VisualEditor.
