The Microsoft © skype continues to bring beautiful crashes after update to the newest version, and here is the only way to overcome them under Fedora 20.
Everything you need is:
sudo yum install control-center-extra pulseaudio-libs.i686 alsa-plugins-pulseaudio.i686 libXv.i686 libXScrnSaver.i686 dbus-qt.i686 qt.i686 qt-x11.i686
Then install skype in a normal way as I describe here. Tested on HP Compaq CQ71 laptop.
Add the skype yum repo repository but do not make it active and use only installing once for non-regular update checks.
