gnome-keyring-daemon uses a lot of memory

1) The version and edition of Linux Mint and version of gnome-keyring:

$ cat /etc/lsb-release
DISTRIB_ID=LinuxMint
DISTRIB_RELEASE=17.1
DISTRIB_CODENAME=rebecca
DISTRIB_DESCRIPTION="Linux Mint 17.1 Rebecca"

$ cinnamon --version
Cinnamon 2.4.7

$ dpkg -l gnome-keyring

2) How to reproduce it.

Start one or more gnome-terminal sessions connected to remote server by ssh and leave them open for at least half an hour or more, e.g. snippet from pstree:

|-gnome-terminal(404)-+-bash(463)
        | |-bash(4195)
        | |-bash(14698)---ssh(14759)
        | |-bash(16908)
        | |-bash(18025)
        | |-bash(19604)
        | |-bash(20717)---man(20779)---pager(20795)
        | |-bash(23307)
        | |-bash(23607)-+-less(24019)
        | | `-pstree(24018)

3) The result in an hour or more is gnome-kerying-daemon process is using almost 1/6 of all of the host memory:

$ ps -p 32051 -o pcpu,pmem,pid,comm
%CPU %MEM PID COMMAND
 1.1 15.8 32051 gnome-keyring-d

$ cat /proc/32051/cmdline
/usr/bin/gnome-keyring-daemon--daemonize--login

If freshly started it is using not more than 1MB or less.

4) The expected is to leave the session for days at a time without any need for gnome-keyring-daemon to be restarted.

5) The problem is reproducible always, just have to leave some terminals open for some time.

Some remarks:
- Tried to reproduce similar behaviour with Ubuntu 14.04 and 14.10 without success.
- The same issue was reproducible also in Linux Mint 17 Qiana. In fact the host was upgraded from Quiana to Rebecca some months ago.
- Logging out and log-in back resolves the issue as the keyring daemon is restarted.
- Attempting to restart just the process results in:
/usr/bin/gnome-keyring-daemon -r --daemonize
