According to my replicated copy of the database, the annotation actually does contain whitespace (a single \r), so this is probably a duplicate of MBS-3416

The \r was removed by me in edit #15417115, after that I filed this issue.

There was still one in the database though, see http://pastebin.com/REcjHZ8j
I just edited the annotation myself and removed it though and now it no longer tries to show the annotation.

It seems that all empty annotations are now shown... whitespace or not :/

This is now happening for all (previously existing) annotations, since the last "fix"

Annotations are now shown, regardless of text content, if there is a history. This was introduced in MBS-1922, as a way to shown a link to the annotation history. I'm marking this decision required, as doing the obvious thing and hiding the annotation would break MBS-1922 again.

The add annotation and edit history links are in the sidebar, I don't see why the annotation history link can't also go in the sidebar.

I think it makes sense to move "View annotation history" under the "Add/Edit annotation". I don't see much use to have it above the tracklist if there is no annotation itself.

Reopening as we seem to have a clear consensus here.

No fix version is specified. Should we expect this to be included in the next release?

Luca: yeah; fix date must not have been set when this went into beta, but if something's in beta testing it should be the next release
