Platform preferences do not update on newer KDE systems

[Michael Strauß]

Change detection on Linux works by listening to the
notify::gtk-theme-name signal (in PlatformSupport.h/cpp). The
g_signal_connect_data documentation states that a warning is emitted
if a signal name doesn't exist. Do you see anything of that sort in
the console?
