The kernel complaining that there is no file system to mount, and
panics. Here is a plain text version of the issue if you want to have
a look[1].

Apologies, we are trying our best to find a happy medium for all
users, and clearly we aren't there yet. We have the ability to provide
plain text e-mail, instead of the multi-part html ones we typically
send out. If that is helpful for you at all, we can setup a hook to
send the plain text e-mails directly to you. Unfortunately, there
isn't much we can do about the javascript elink issue without
re-writing the front end :\
