This bug was fixed in the package unity - 5.2.0-0ubuntu2

---------------
unity (5.2.0-0ubuntu2) precise; urgency=low

  * Cherry-pick upstream:
    - a fix for a 5.0 crasher (LP: #916228)
    - default configuration now to "always lock"
  * debian/profile_upgrade/com.canonical.unity.unity.03.upgrade,
    debian/unity-common.install:
    - enabling user profile upgrade installation
    - switcher per workspace is now the default on upgrade
    - launcher is always locked by default, even on upgrade (LP: #928153)
