Comment # 10 on bug 1141444 from Jiri Slaby

Well, with ASAN disabled and the patch, clementine is now at 223 MB and doesn't
grow much. I still see leaks in plugins, leaking Network objects. It's 84 files
to edit (most of the plugins), so it will take some time.

For example ArtistBiography or Musicbrainzcover:

There seems to be a repetitive problem with fontrendering (fontconfig), which I
will into later. This perhaps makes clementine memory footprint to grow.
