In Windows XP I installed 2.2.0 using a non-admin user account and get NPEs
when trying to do a component search or when clicking on the Sources button.

As background: during installation you're prompted as to which user you want to
install as. I installed as this non-admin user, and since this user can't write
to Program Files, I installed into a directory in this user's home dir
(Documents and Settings\etc). Also, XP gives you an option to "protect my
computer and data from unauthorized program activity" when installing -- I
unchecked this, in hopes of avoiding any issues.

As this non-admin user, I also tried installing in a different way - when
prompted on which user to install as, I installed into Program Files as an
admin user. Surprisingly the two types of NPEs still occur.

When you try to do a Component Search, you get:
