Pluggo AU Scan fails to see plugins

Hi Everyone,

I'm having a problem where the Pluggo AU Scan fails to scan or
recognize all of the plugins that I have in my Pluggo folder.
The AU scan application seems to arbitrarily skip over certain
plugins each time i run the scan (different ones are skipped each
time). It is quite unpredictable, and often fails to see even the
original set of Pluggo plugins (those bundled with pluggo) not just
3rd party or self-developed ones. As a result, the AU validation
application in Logic doesn't see them as installed either. The
plugins all appear when i load them into applications other than AU
applications. Has anyone else had this problem? Is this a bug or a
result of something stupid that I am overlooking? I googled the
subject, but couldn't find anything pertaining specifically to this
issue. I don't recall this happening before 3.5.3, but am not
certain...
I think the issue is with the Pluggo scan rather than the AU val
program in Logic. When i run the AU manager in Logic 7, the omitted
pluggos are listed as 'not installed' and selecting it indicated a
"fatal errow: did not locate component."

I would greatly appreciate any help/advice,

Dual 2Ghz G5
OSX 10.4.4
Pluggo 3.5.3
Logic 7.1.1
Max/MSP 4.5.6
Motu 828 MK2

Summary: see above

Steps to reproduce: 1) run AU Scan... closely monitor the
scanning process and notice it skipping certain plugins
                    2) open Logic 7 and open pluggo plugin list....notice missing
plugins.

Expected results: That all pluggo plugins would appear in AU
application.

Actual results: Certain pluggos were omitted/not recognized by
the scan and thus do not appear in AU host such as Logic 7.
