I'm using liferea 1.8.10 on Fedora 17 and I'm seeing a weird effect on the liferea icon in Gnome's notification bar.
When I run liferea, the icon appears but seems cropped in two directions (see enclosed screenshot).
Going to the preferences, I can disable the icon which then disappears.
Clicking on the "Show status icon" again, the icon reappears but this time, fully formed (again, see enclosed screenshot)
Closing liferea and starting it up again takes me back to the starting point (the icon is again cropped)
