Affects: ubuntu-artwork (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
Changing icon theme from Clearlooks to Ubuntu Human in Dapper makes the
colours in gnome-panel and some menu bars (such as in GNOME Terminal) go
psychedelic, as if the colour map is wrong.  Screenshot attached.

I was able to solve this problem by following Sebastien Bacher's advice
in response to another bug (#23162):

running sudo gtk-update-icon-cache /usr/share/icons/hicolor
restarting gnome-panel
and then
restarting all running GTK applications with crazy colours

but this is more effort than it should be.  Could Breezy upgraders with
a window theme like Clearlooks experience this when they try to change
to Human, or will the appropriate caches be refreshed automatically?
