Dear Maintainer,

when the day changes iceowl doesn't change to the current day.
E.g. when the day changes from 4.2 to 5.2 I still see 4.2 as today and dates
for today are shown as dates for tomorrow. I have to click on the circle-symbol
to refresh iceowl and get a correct view.
This also happens if I uninstall iceowl and use lightning instead. So I tagged
it as 'upstream'.
This is no really harmful bug, but it get's annoying if you have to click at
the circle symbol (or restart icedove) every day.

Best regards
Martin
