[Users] Has something changed with the sort of the email list?

[sylpheed at 911networks.com]

Hi,

I use 3.11.1 (with the default internal theme) on xubuntu 14.04. I've
been using 3.11.1 since a week after its release. I just noticed now
that the message list has the triangle on the columnS: subject, from,
to, date.

It used to be only on the column that was sorted. Now, I don't know
on which column is the email list is sorted. When did this happen?
Anything I can do about it?
