Problem is really maybe there (chm.c:LoadWinTypeFromCHM). IStorage_OpenStream
actually fails and info->pCHMInfo->defTitle is NULL in that block, so you do
strdupW(NULL) which returns NULL.

hr = IStorage_OpenStream(pStorage, windowsW, NULL, STGM_READ, 0, &pStream);
if (FAILED(hr))
{
    ...
    info->WinType.pszCaption=strdupW(info->pCHMInfo->defTitle);
    ...
    return TRUE;
}

And please ignore my previous comment, perhaps there are stored indexes until
they are replaced (?)
