In following bib file misses the comma after the field value (American Mineralogist) for journal:

❯ cat my2.bib
@Article{Dove:1997,
  author  = {Dove, Martin T.},
  title   = {{Theory of displacive phase transitions in minerals}},
  doi     = {10.2138/am-1997-3-401},
  issn    = {0003-004X},
  journal = {American Mineralogist}
  month   = {apr},
  number  = {3-4},
  pages   = {213--244},

v2.67 and commit 4120397 are affected.
