Does the attached patch fix the problem?

Subject: [PATCH] org-bibtex-yank: Fix bibtex parser not initialized in temp
 buffer

* lisp/ol-bibtex.el (org-bibtex-yank): Make sure that we parse bibtex
entry from the kill ring in a `bibtex-mode' buffer.  Otherwise,
calling `org-bibtex-read' (that calls `bibtex-parse-entry') may err
because some Bibtex parser variables are not initialized.
