Are you sure it doesn't depend on the number of results you're giving back?

If not we will need the scope you're using to reproduce the error

[Jin (jindallo)]

I am sure,
since the number of results > 10 as I configured.

You could use Today aggregator to see the results from Holidays scope here:
    https://code.launchpad.net/~todayscope-team/today-scope/trunk
    https://code.launchpad.net/~holidays-scope-team/holidays/trunk

The Holidays is shown by vertical-journal,
and you could check the behavior on the issued button.

Sorry my bad, what counts to decide if to show the more/less button is not the number of results you're giving back, what counts is how tall those results are.

I don't get any holidays on my today scope, so it doesn't work as a way to reproduce the error. Do you think you can produce something that is not dependant on the day of today and always reproduces this error?
