Python Clearlooks issue

(<unknown>:127729): Gtk-WARNING **: Unable to locate theme engine in module_path: "clearlooks"

This error seems to happen because some some configuration file has specified that the default Qt theme should be "clearlooks".  But Qt doesn't have one called "clearlooks" - it is supposed to be "cleanlooks" (with an N).  It seems like somebody typed the mis-spelled version into the config file.

You can change this default using the 'qtconfig-qt4' tool.  Open it up, and on the 'appearance' tab, set 'Select GUI Style' to 'Cleanlooks'.  A very strange glitch happens when you do this, and changes the font to Papyrus, so you also need to go into the 'fonts' tab and select 'Sans Serif' as the default font family (point size 10).  I went ahead and did this today, and it seems like everything is back to normal.
