Bug #: 31016
           Summary: HTML Help does not properly handle index entries with
                    the same name
           Product: Wine
           Version: 1.5.7
          Platform: x86
               URL: http://www.microsoft.com/en-us/download/details.aspx?i
                    d=5210
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: hhctrl.ocx
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

Duplicate entries in the HTML Help index appear as multiple entries.  This
should not be the case, all of these entries should appear as part of the
"Topics Found" dialog.

Steps to reproduce:
0) At this time you must first patch Wine with the attachment to Bug #30948.
1) Download ContentAPISetup.msi from the MS website
2) cabextract -F _4E8D3D4C602B47F5A445D1B7AABCFE9F ContentAPISetup.msi
3) mv _4E8D3D4C602B47F5A445D1B7AABCFE9F ContentAPISetup.chm
4) wine start ContentAPISetup.chm
5) Switch to the Index tab
6) You'll notice many duplicate entries ("ContentException constructor" is a
good example)
