[Evolution] evo-calendar doesn't show up

[THUaN <thuan gmx fr>]

hello,

i recently upgrade from evo 1.2 to evo 1.4 -- which is very nice for the eyes. but the upgrade comes with one trouble : when i click on calendar, i only see the task board (without the input line). 

i worked around a bit and i found this thing : after trying to see my calendar, i wanted to display the calendar by day, by working week, by month. and evolution still crashes everything i do this.

could someone help me fixe this thing ?

thanks
luna
