    Description

      Dropping URLs from certain sources result in corrupted URLs (mimeData()->urls()) in Qt 5. Qt 4.8.7 works fine here.

      Steps to reproduce:
      1. Launch the attached test program python drop.py 5 (Qt 5, broken) or python drop.py 4 (Qt 4, working).
      2. Open https://askubuntu.com/ in Firefox or Chromium.
      2. Drag and drop a URL from a page, from a bookmark and finally from the location bar to the program.

      Expected result (for Urls at least):

      Formats: ['text/x-moz-url', 'text/uri-list', '_NETSCAPE_URL', 'text/x-moz-url-data', 'text/x-moz-url-desc', 'text/html', 'text/unicode', 'text/plain;charset=utf-8', 'text/plain']
      Text: 'https://askubuntu.com/'
      Urls: [PyQt4.QtCore.QUrl('https://askubuntu.com/')]
      uri-list: PyQt4.QtCore.QByteArray(b'https://askubuntu.com/')
      
      Formats: ['text/x-moz-place', 'text/x-moz-url', 'text/uri-list', '_NETSCAPE_URL', 'text/unicode', 'text/plain;charset=utf-8', 'text/plain', 'text/html']
      Text: 'https://askubuntu.com/'
      Urls: [PyQt4.QtCore.QUrl('https://askubuntu.com/')]
      uri-list: PyQt4.QtCore.QByteArray(b'https://askubuntu.com/\r')
      
      Formats: ['text/x-moz-url', 'text/uri-list', '_NETSCAPE_URL', 'text/unicode', 'text/plain;charset=utf-8', 'text/plain', 'text/html']
      Text: 'https://askubuntu.com/'
      Urls: [PyQt4.QtCore.QUrl('https://askubuntu.com/')]
      uri-list: PyQt4.QtCore.QByteArray(b'https://askubuntu.com/')
      

      Actual result:

      Formats: ['text/uri-list', '_NETSCAPE_URL', 'text/x-moz-url-data', 'text/x-moz-url-desc', 'text/html', 'text/unicode', 'text/plain;charset=utf-8', 'text/plain']

      Formats: ['text/x-moz-place', 'text/uri-list', '_NETSCAPE_URL', 'text/unicode', 'text/plain;charset=utf-8', 'text/plain', 'text/html']
      Text: 'https://askubuntu.com/'
      Urls: [PyQt5.QtCore.QUrl(''), PyQt5.QtCore.QUrl('%00A%00s%00k%00 %00U%00b%00u%00n%00t%00u')]

      Further information:
      Chromium is more severely affected, all of its URLs are wrongly detected:
