Google Scholar [patch]

[fbennett]

This is a patch that will get Google Scholar working again. Apologies for submitting in this form: I need to shift my MLZ translator repo to a branch, but I've been putting off the work because it will impact the MLZ update chain, and I don't currently have time for the debugging.

Anyway, here is the patch.

Cheers,
Frank
