Error caused by permissions ?

Hi,
        1. Started IDEA using sudo ./idea
        2. Started  by clicking on the menu.

Could there be a permission issue  here ? There was a popup showing some permission problem. I turned on full rights for all uses after this and then I saw this error.


Thanks,
Mohan
