[PyQt] isSystemTrayAvailable() causes segfault

[Philip Lorenz]

Have you created a QApplication instance before attempting to call that 
function. I am also running ArchLinux (AMD64) and am only experiencing a 
segfault in XInternAtom () from /usr/lib/libX11.so.6 if a QApplication 
instance does not exist (the segfault also happens when using Qt without 
any bindings at all - so it's probably a bug in Qt itself).

Sample #1 (segfaults):

from PyQt4 import QtGui

QtGui.QSystemTrayIcon.isSystemTrayAvailable()

Sample #2 (does not segfault):

from PyQt4 import QtGui
import sys

app = QtGui.QApplication(sys.argv)
print QtGui.QSystemTrayIcon.isSystemTrayAvailable()
