[Gabriele Svelto [:gsvelto]]

There's a few URLs coming up more than once in the crash reports:

• https://www.caisse-epargne.fr/particuliers
• https://login.japannetbank.co.jp/wctx/LoginAction.do?loginIdFlg=0
• https://retail.santander.co.uk/olb/app/logon/access/#/logon

The second one in particular shows up 6 times.
