memory and file descriptor (zeitgeist/activity.sqlite) leak in empathy

[Leonid Evdokimov]

empathy process takes almost 1G of RSS memory, that's way too much and looks like leak as soon as RSS grows over time.

Another symptom is lots of duplicate open files, $HOME/.local/share/zeitgeist/activity.sqlite is opened 160 times according to lsof:
$ lsof -p 3970 | awk '{print $(NF)}' | sort | uniq -c | awk '($1 > 1)'
      8 anon_inode
      2 /dev/pts/27
    160 /home/darkk/.local/share/zeitgeist/activity.sqlite
      2 /home/darkk/.local/share/zeitgeist/activity.sqlite-shm
    160 /home/darkk/.local/share/zeitgeist/activity.sqlite-wal
      2 pipe
      6 socket
      2 /SYSV00000000

Full lsof output is attached as lsof.txt
