Can't call method "textContent" on an undefined value

[MrkGrgsn]

As of 0200 UTC+10, the Scopus plugin is dying with the following:

[quteprints scopus] Error: Unhandled exception in Import::CitationService::Scopus: Can't call method "textContent" on an undefined value at .../archives/quteprints/cfg/plugins/EPrints/Plugin/Import/CitationService/Scopus.pm line 248, <$fh> line 1437.

This appears to be an upstream issue; the web service is returning an incorrect returnedResults value - it is returning '25' whether totalResults is zero or more. I have reported to Scopus Integration, placing it here for user visibility.

Feedback from Scopus Integration is that a ticket has been raised.

I'm not sure whether Scopus have resolved this or not - I haven't heard back - but it's closed by 1e29050 anyway

Even though it has no impact on the citation plugins, I'm just noting that Scopus have resolved this bug in their web service now.
