Clicking on date in calendar applet fails to open evolution window in Feisty

Binary package hint: evolution

Recently upgraded to feisty, and clicking on a date in the calendar applet no longer opens an evolution calendar window. If I try on the terminal, typing "evolution" successfully opens a window and gives me this output:

<<
GTK Accessibility Module initialized
Bonobo accessibility support initialized
CalDAV Eplugin starting up ...

(evolution-2.10:25860): evolution-mail-WARNING **: ignored this junk plugin: not enabled or we have already loaded one

(evolution-2.10:25860): e-utils-WARNING **: Plugin 'Spamassassin junk plugin' failed to load hook 'org.gnome.evolution.mail.junk:1.0'
(evolution-2.10:25860): e-data-server-DEBUG: Loading categories from "/home/joseph/.evolution/categories.xml"
(evolution-2.10:25860): e-data-server-DEBUG: Loaded 30 categories

[after closing the window:]
process 25860: The last reference on a connection was dropped without closing the connection. This is a bug in an application. See dbus_connection_unref() documentation for details.
Most likely, the application was supposed to call dbus_connection_close(), since this is a private connection.

However, typing "evolution calendar:///?startdate=20070508T120000" (the event generated by clicking on the calendar applet) causes only this output in the terminal:

<<
GTK Accessibility Module initialized
Bonobo accessibility support initialized
CalDAV Eplugin starting up ...
>>

but opens no window.

Thanks
