This update for cinnamon fixes the following issues:

Security issue fixed:

- CVE-2018-13054: Fix symlink attack vulnerability (boo#1083067).

Bug fixes:

- Update to version 3.4.6 (changes since 3.4.4):
* osdWindow.js: Always check the theme node on first showing - an
actor's width isn't necessarily filled if it hasn't been
explicitly set, causing the first few activations of the OSD to not show an accurate level bar.
* cs_default: Fix an incorrect button label (but preserve translations).
* main.js: Remove an obsolete Meta enum member reference.
* workspace.js: Use our normal prototype init method.
* workspace.js: Initalise WindowClone._zoomStep to 0.
* slideshow-applet: Fix a translation.
* cs_themes.py: Create the file "~/.icons/default/index.theme" and
set the selected cursor theme inside of it. This ensures other
(non-gtk) applications end up using the same theme (though they
are required to be restarted for these changes to take effect).
* keyboard-applet: Applet icon vanishes when moved in edit mode.
* cinnamon-json-makepot: Add keyword option, change language used by xgettext to JavaScript.
* expoThumbnail: Correct a couple of calls with mismatched argument counts.
* window-list: Set AppMenuButtons unreactive during panel edit mode.
* panel-launchers: Set PanelAppLaunchers unreactive during panel edit mode.
* windows-quick-list: Fix argument warning.
* Fix a reference to undefined actor._delegate warning.
* ui/environment: Handle undefined actors in containerClass.prototype.add.
* ui/cinnamonDBus: Handle null xlet objects in CinnamonDBus.highlightXlet.
* deskletManager: Initialise some variables and remove the
variables that were initialised, probable typo
