Description of problem:
The latest update of gtk3 breaks gtkdoc-depscan for gtk3 and gdk3 devhelp books.  This seems to be caused by property descriptions

<keyword type="property" name="The &quot;default-display&quot; property" link="GdkDisplayManager.html#GdkDisplayManager--default-display"/>

changed to

<keyword type="property" name="The “default-display” property" link="GdkDisplayManager.html#GdkDisplayManager--default-display"/>

in .devhelp2 files.  Note the different representation of quotes (entities vs Unicode).


Version-Release number of selected component (if applicable):
gtk3-devel-docs-0:3.10.8-1.fc20


How reproducible:
Always.


Steps to Reproduce:
1. Create a C program bug.c with the following content:

void bug(void);

2. Run

gtkdoc-depscan -b gtk3 bug.c


Actual results:
It crashes with
Traceback (most recent call last):
  File "/usr/bin/gtkdoc-depscan", line 351, in <module>
    symbols.update(book.symbols)
  File "/usr/bin/gtkdoc-depscan", line 87, in _get_symbols

  File "/usr/bin/gtkdoc-depscan", line 201, in from_xml
    type, name = 'property', '%s::%s' % (owner, name.split('"')[1])
IndexError: list index out of range


Expected results:
It passes.


Additional info:
gtk3-devel-docs-0:3.10.7-1.fc20 is OK.

This is most likely a gtk-doc problem, however, the change was in the gtk3 package.  The installed version of gtk-doc on my systems has not changed and it is still gtk-doc-1.19-4.fc20 which is the latest version.

The gtk3 package .devhelp2 file states to be generated using "GTK-Doc V1.20.1 (XML mode)", i.e. a newer gtk-doc than available in updates-testing.

As more packages are rebuilt, more problems of this kind are to be expected.  Maybe a new gtk-doc package will fix it, however, the new .devhelp2 files are incompatible with the current gtk-doc.
