Look up button & DOI metadata fetcher

[David Coeurjolly]

Hi John & referencers,

I've troubles with the DOI look up button: the button is always
disabled. Bug #133074 seems to report the problem but the patch does not
work (probably because I applied it to SVN rev551 instead of 542).

By the way, I'd like to use the DOI metadata fetcher with a crossref
account (see workaround in bug #138024) but neither the button
(disabled), nor the "Add Ref with DOI" command fetch the data: if I
enter a ref with DOI, I obtain the following Warning:

Warning: DocumentList::getDoc: couldn't find doc with name 'Unnamed'

And the 'Unnamed' entry hasn't got any metadata....

Note that the CrossRef workaround works because if I use the Pref
openurl address in my browser, I obtain the correct XML data.

any Idea ?
