Description of problem:
gnome activity journal doesn't start on Fedora, instead I get an error:

Version-Release number of selected component (if applicable):
gnome-activity-journal-0.8.0-2.fc17.noarch
libzeitgeist-devel-0.3.18-1.fc17.x86_64
libqzeitgeist-0.8.0-6.fc17.x86_64
zeitgeist-datahub-0.7.0-4.fc17.x86_64
libzeitgeist-0.3.18-1.fc17.x86_64
zeitgeist-0.9.0-1.fc17.x86_64


How reproducible:
start zeitgeist  with zeitgeist-daemon --replace, then start gnome-activity-journal,  get a stacktrace.

According to Seiflofty on IRC it is a version mismatch ( too old Zeitgeist ).
