Comment 6 for bug 1532415

Workarounds include
1. Remove the chrome.favicons lines from google_chrome.xml and chromium.xml
2. Whitelist the file Favicons files in the BleachBit preferences

Analysis notes
- Chromium 60 on Linux and Google Chrome 46 stores Bookmarks in JSON format in a file called Bookmarks. BleachBit does not need this file
- Favicons are stored in an SQLite database called Default/Favicons
- In the older version, Google Chrome 46, icons are always 16x16 pixels in the table favicons_bitmaps
- In the newer version, Chromium 60, icons are 16x16 and 32x32 pixels, so there are twice as many rows in favicons_bitmaps
