Error: Permission denied

After installed KILE, and open KILE, a error displayed:
"Unable to save bookmarks in /home/me/.kde/share/apps/kfileplaces/bookmarks.xml. Reported error was: Insufficient permissions in target directory.. This error message will only be shown once. The cause of the error needs to be fixed as quickly as possible, which is most likely a full hard drive."

Solution:
$sudo chmod -R 777 /home/me/.kde

Note: donot forget "-R"
