You can try to see whether the effective permissions for your user actually 
give you access. You can also try to remove acl support for the file system. 
In /etc/fstab, remove the acl option, if there is one.

There's one instance in which I actually needed ACLs. My sisters were using my 
desktop as a gaming machine (as opposed to doing their homework and such). So 
I went ahead and put them all in a group which I denied access to the games to 
without having to touch the pre-defined permissions for other users.
But that's the only time ACLs were ever necessary for me.
