There is a bug with the GMail 2.2.3 simple message purge (the advanced message purge is okay) that purges ALL messages instead of just the indicated number of messages. The attached file, which replaces admin/GMail/Admin/Purge.pm, should fix the problem.
The GMail 2.2.3 package available for download has, as of this post, been updated with the fix.
