Happens on every restart.

Completely deleted user profile as well as uninstalled and reinstalled Chrome.  Issue still persists 	

Found the what happens but not quite sure why or how to fix it:

bool TokenServiceTable::SetTokenForService(const std::string& service,
                                           const std::string& token) {
  std::string encrypted_token;
  bool encrypted = OSCrypt::EncryptString(token, &encrypted_token);

// encrypted equals false here due to CryptProtectData in os_crypt_win.cc#OSCrypt::EncryptString returning 0 with last error = 0x80090345
// The requested operation cannot be completed. The computer must be trusted for delegation and the current user account must be configured to allow delegation. 
// Samba 4 based AD server domain is used on the PC

  if (!encrypted) {
    return false;
  }

Looks like the culprit was: https://bugzilla.samba.org/show_bug.cgi?id=11097

Upgrading to 4.5.1 solved the problem. Though it would be nice if chrome gave some indication if OS level encryption was not working
