[Evolution] Evolution not starting

[SanthanaKrishnan <n santhan arasans in>]

Dear All,

We use evolution mail in our small office of 20 staff. In one system
evolution would not start and I re installed. 

Now it says "evolution: symbol lookup error: evolution: undefined
symbol: ical_set_unknown_token_handling_setting ". 

I tried removing and re-installing again to no avail. What do I do to
run evolution.
