Setting the figure format requires setting all format types in numfig_format

[misev]

Problem

Changing the 'figure' format with numfig_format requires listing all other formats as well, otherwise an exception will be thrown.

Procedure to reproduce the problem

In conf.py set numfig_format={'figure': 'Figure %s'}, then try to build a document which has some figures and tables.

Error logs / results

Exception occurred:
  File "/usr/lib/python2.7/dist-packages/sphinx/writers/html.py", line 279, in append_fignumber
    self.body.append(prefix % numsstr + ' ')
TypeError: not all arguments converted during string formatting
The full traceback has been saved in /tmp/sphinx-err-PjF2Qy.log, if you want to report the issue to the developers.

Workaround

Specify all formats:

numfig_format = {'figure': 'Figure %s', 'table': 'Table %s',
                 'code-block': 'Listing %s', 'section': 'Section %s'}
