No problem. Thanks for the tips to replicate this. It was pretty helpful
in solving the problem (and thanks again to Nick who pointed me towards
edebug-defun a while ago!)

I think I have fixed this. The problem was org-ref was not finding a key
that exists in a file. the way that is done all over org-ref is to
insert the contents of the bibfile in temp buffer, and then use
bibtex-search-entry on that buffer. It works like a charm usually, but
not in the replicated steps you have below. once it works once, though,
it seems to always work. 

Anyway, I think it is fixed now. there is a new version at

Thanks for reporting the bug!
