I had this problem after a relatively recent upgrade from 2.1 to 2.2
on a Windows machine.  It seems that the "rebase" plugin has been
renamed to (or possibly merged into) the "rewrite" plugin and when you
upgrade Bazaar with the Windows installer, it doesn't remove the old
plugin.  As a result, you have the rebase functionality provided by
the rewrite plugin and an old plugin that hasn't been touched and
still expects Bazaar 2.1 to be present.

A simple workaround is to delete the c:\Program
Files\Bazaar\plugins\rebase directory.  However, I don't know anything
about the sql file error: that looks like a different problem.
