Hi Ivan,

I gave your patch a test ride and playing videos in IceCat now correctly
inhibits the screensaver. Thanks!

I adjusted the commit message a bit and pushed the patch to master:

    gnu: icecat: Add libxscrnsaver to runtime LD_LIBRARY_PATH

    IceCat loads libXss.so at runtime to inhibit screen locking if other interfaces are unavailable.

    * gnu/packages/gnuzilla.scm (icecat)[arguments]: Add libxscrnsaver to
    wrap-program arguments.
