It appears to be the same case-sensitivity bug as before :/

I've created a user with mixed case username but I still can't manage to 
reproduce this running locally. Anyone 
else?

I don't believe we'll ever be able to reproduce this problem. It only happens to
people who have accounts on jaiku.com that have been migrated. My guess is that
something went wrong and now the normalized_nick for these users is not 
lowercase.

For example look at this post:
http://www.jaiku.com/channel/jaiku/presence/a4e5edd6da134cc9b1a1c371da825dc1 
Note
that the user does exist and has a url with a lowercase domain name which works.
Here's what seems to be happening: In various places in the codebase (to do with
changing backgrounds, changing passwords and sending invites) we're using the
unnormalised/mixed-case nickname of the user and this is failing to find a 
match.
However when we report the error we use normalised/lower-case name of the user.

Andy: Can you use the AppEngine data-viewer and examine the Actor entity for the
affected users. Do they have lower-case normalized_nick values? It might also 
be a
good idea to dig up the migration code and find out if it did anything special 
when
migrating users with mixed-case usernames.

Looks like I was wrong. This new user: 
http://www.jaiku.com/channel/jaiku/presence/62553f0098954e75b70149d741ad244b is 
suffering from the 
same bug. He has a mixed-case username but his account didn't go through the 
data migration process.
