As posted in Message #43, it is in fact because
of /usr/share/revelation/libexec/revelation-applet . I copied the version
from 10.04 and overwrote /usr/share/revelation/libexec/revelation-applet on
my 11.04, reloaded the applet, and the icon is drawn. Here is the diff on
the two files:

< if "/usr/lib/python2.7/dist-packages" not in sys.path:
< sys.path.insert(0, "/usr/lib/python2.7/dist-packages")

> sys.path.insert(0, "/usr/lib/python2.6/dist-packages")
