No, I don't know what "ext2manager" is. What is it for? But I see why you don't get the same errors as I do with N9QT, the permissions on your MyDocs directory are messed up... world writable, group is root. That is why root can write to your MyDocs. In fact, if you were to try the suggestion you gave me... `chown -R user:users MyDocs', you would see the bug I reported with N9QT.
chown -R user:users
