This is just a guess, and is probably not the issue.  But perhaps you ran it 
as root at one point, and it created files in your homedir (or a subdirectory 
thereof) that belong to root (and you're now not able to change them)..

If you no files in your homedir that should belong to any other user than 
yourself, do:

sudo chown -R :plugdev <homedir>

..replacing <homedir> with the path to your home directory, such as:

sudo chown -R :plugdev /home/mikko

The bug you are experiencing, though, is a separate bug from the one this 
bugreport is for, and any further correspondence on it should go in a 
separate bugreport.
