This bug was fixed in the package unity-control-center - 14.04.3+14.04.20140317-0ubuntu1

---------------
unity-control-center (14.04.3+14.04.20140317-0ubuntu1) trusty; urgency=low

  [ Robert Ancell ]
  * Only allow icons sizes to be even numbers because odd sizes look
    blurry. (LP: #991310)

  [ Sebastien Bacher ]
  * Backport some leak fixes from upstream, those were leading to
    dialogs not closing when they should (e.g when exiting the panel
    they belong to), hitting a segfault when used then. (LP: #1292038)
  * Use the correct naming for the "Text Entry" settings
  * handle pa_stream_peek returning null (LP: #1197029)
