failure to raise DisambiguationError for "Leaching" page on Wikipedia

See original GitHub issue

Using pymediawiki 0.3.15 with Python 3.6.3 on Linux, I observed the following error when attempting to access the disambiguation page for “Leaching” on Wikipedia.

python -c "import mediawiki; wikipedia=mediawiki.MediaWiki(); wikipedia.page('Leaching')"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/lebedov/miniconda3/lib/python3.6/site-packages/mediawiki/mediawiki.py", line 731, in page
    preload=preload)
  File "/home/lebedov/miniconda3/lib/python3.6/site-packages/mediawiki/mediawikipage.py", line 72, in __init__
    self.__load(redirect=redirect, preload=preload)
  File "/home/lebedov/miniconda3/lib/python3.6/site-packages/mediawiki/mediawikipage.py", line 532, in __load
    self._raise_disambiguation_error(page, pageid)
  File "/home/lebedov/miniconda3/lib/python3.6/site-packages/mediawiki/mediawikipage.py", line 569, in _raise_disambiguation_error
    one_disambiguation['title'] = item[0]['title']
  File "/home/lebedov/miniconda3/lib/python3.6/site-packages/bs4/element.py", line 1011, in __getitem__
    return self.attrs[key]
KeyError: 'title'

Relatedly, wikipedia 1.4.0 correctly raises a DisambiguationError exception for the above.

Great catch, I hadn’t looked at the title portion in awhile. Would you like to open a new issue so that we can track this? Thanks!

@barrust : here’s an example for “Lincoln Museum” (https://en.wikipedia.org/wiki/Lincoln_Museum):

from mediawiki import MediaWiki, DisambiguationError
wikipedia = MediaWiki()

try:
    p = wikipedia.page("Lincoln Museum")
except DisambiguationError as d:
    print(d.details[5]['title'])
    print(d.details[5]['description'])

I’d expect the title here to be only “Ford’s Theatre” since that’s the title of the link, but instead the title is the same as the full description (both are Ford's Theatre, Washington, DC, USA — where Abraham Lincoln was assassinated; known as Lincoln Museum from 1936 to 1965 and legally "Ford's Theater (Lincoln Museum)" since 1965).

In [8]: print(mediawiki.__version__)
