I ran it through valgrind by diverting indicator-session-service and
replacing it with the following script:

#!/bin/bash

exec valgrind \
    --tool=massif \
    --alloc-fn={g_slice_alloc,g_malloc,g_realloc} \
    --massif-out-file=$HOME/massif-dump/indicator-session-service.out.%p \
    /usr/lib/x86_64-linux-gnu/indicator-session/indicator-session-service.distrib \
    "$@"

Running ms_print on the output files gave me some stack traces of the
highest number of unfreed allocations:

Title:
  indicator-session is leaking memory on ubuntu 15.10

Status in indicator-session package in Ubuntu:
  Incomplete

Bug description:
  The `indicator-session-service` is slowly leaking memory, after a
  while it has used up over 10 gigabytes of RAM and swap and the entire
  system freezes.

  I've reinstalled the entire OS, and even started using a new home
  folder, but it's still happening.
