Fixing Qt appearance under XFCE 4.8 (aptosid)

On my aptosid setup running Xfce, Qt apps don't honor the GTK appearance setting without some help. The post at http://forum.xfce.org/viewtopic.php?id=5605 provides a solution that worked for me:

# echo 'export GTK2_RC_FILES="$HOME/.gtkrc-2.0"' >> /etc/profile.d/qgtkstyle.sh
# chmod 755 /etc/profile.d/qgtkstyle.sh

then logout and back in.

With Xfce taking on increasing importance since the introduction of GNOME 3, I hope this will work out-of-the-box in the near future.
