 #  NIXOS KDE STARTUP SCRIPT
 #
 
+# The KDE icon cache is supposed to update itself
+# automatically, but it uses the timestamp on the icon
+# theme directory as a trigger.  Since in Nix the
+# timestamp is always the same, this doesn't work.  So as
+# a workaround, nuke the icon cache on login.  This isn't
+# perfect, since it may require logging out after
+# installing new applications to update the cache.
+# See http://lists-archives.org/kde-devel/26175-what-when-will-icon-cache-refresh.html
+rm -fv $HOME/.cache/icon-cache.kcache
+
+# Qt writes a weird ‘libraryPath’ line to
+# ~/.config/Trolltech.conf that causes the KDE plugin
+# paths of previous KDE invocations to be searched.
+# Obviously using mismatching KDE libraries is potentially
+# disastrous, so here we nuke references to the Nix store
+# in Trolltech.conf.  A better solution would be to stop
+# Qt from doing this wackiness in the first place.
