 Are you sure that Sonata is trying to write to ~/.config ?

 The log shows -- Permission denied:
 '/home/olpc/isolation/1/uid_to_home_dir/10000/.config/'

 Unless there was a link that I failed to notice, that looks like a write
 to a directory in the "isolation" subtree.  [But you are saying that
 Sonata should NOT be writing there, either.]

 My understanding of Rainbow is that it "isolates" Activities from each
 other by assigning each to a unique 'group'.  Might there have been an
 ownership mis-match in the "isolation" subtree ?  [I believe I've seen
 other Activities having created directories and files within the
 "isolation" subtree.]


 If you are right about Sonata storing its configuration data in the wrong
 directory, how come my system is not impacted by Sonata in the situation
 when I have Rainbow turned off ?
