LearnLoop

The real theme names should show up when importing users.

I thought the name of the "default" theme was "Learnloop-theme" which it
says under admin preferences and imported 25 users.
When logging in as one of those users LL went bananas.
Just change the theme name to something that doesn't exist and you should
get the same error.

The error trap should possibly be that when importing users from an
external file and the theme name doesn't exist it should be set to the
default theme.
