    gnu: kcrash: Work around race condition when starting Xvfb.
    
    Sometimes tests would start running before Xvfb is listening.
    See <https://hydra.gnu.org/build/1750201>.
    
    * gnu/packages/kde-frameworks.scm (kcrash)[arguments]: In
    'start-xorg-server', add 'sleep' call after starting Xvfb.  Pass "Xvfb"
    to 'system' instead of its absolute file name.
