According to the documentation the .bib is automatically added to the names in the CITE_BIB_FILES. In the example given with this bug this was not the case.

Tcl: collect XRefs also if INLINE_SOURCES = no

- Open() replaced by xopen() that internally uses the encoding argument
  only for Python 3. The earlier usage of the codecs module and of the
  prefixed unicode string literals was removed.
- Some lists of prototypes were sorted to get the same translator report
  for different versions of Python.
- The local dedent() definition was replaced by textwrap.dedent().
  (The older versions of Python did not have the module.)
- Tested on Windows for Python 2.6.0, 2.7.7, 3.0.1, and 3.4.1.
