I haven't looked at the code, but if it is wrapping all your mail up
in memory before you download the archive, then you're always going to
have this problem when the messages you selected add up to more than
your memory_limit in php.ini.  You could try increasing that setting,
but I don't think that's a very good solution.  It would be better to
attempt to create the archive in a process not limited by the php.ini
memory limit.  Again, I have not looked at the code.

If you want them fixed (for the other plugins), post the
notices/errors in a different thread.  You should upgrade to 1.4.10
FYI.
