An application is closed if manually removed from favorites on gsettings

Bug Description

1) Open an application (say gnome-terminal) and lock it to the launcher
2) Now, edit the gsettings key favorites on com.canonical.Unity.Launcher
removing the gnome-terminal.desktop instance

Expected behavior:

3) The icon is now unlocked from launcher (i.e. right-clicking on it, there's
again a "Lock to launcher" quicklist item, or closing the application, the icon is removed)

Actual behavior:
4) The application is closed (and unlocked)

This bug was fixed in the package unity - 6.2.0-0ubuntu1

unity (6.2.0-0ubuntu1) quantal-proposed; urgency=low

[ Adam Conrad ]
* Removed debian/patches/libgeis-rename.patch

[ Łukasz 'sil2100' Zemczak ]
* debian/rules:
- added override for dh_shlibdeps to point it to the private directory of
libunity-protocol-private.so
* debian/unity.lintian-overrides,
debian/libunity-core-6.0-5.lintian-overrides:
- added override to silence the binary-or-shlib-defines-rpath error, since
we are forced to use RPATH in our case
