Clicking on a date does not start evo anymore, neither does clicking on a task. The commands that the applet is using here are evolution calendar:///?startdate=20070417 or evolution task:200 Upstream bug tracking this is http://bugzilla.gnome.org/show_bug.cgi?id=407104
I reported some observations on this upstream: http://bugzilla.gnome.org/show_bug.cgi?id=407104#c4 I want to ask someone upstream about this before I pick a solution.
Fixed in evolution-2.10.1-6.fc7.
