Disk Management Tool error in Disk Utility

Question

Update: (first, reviewing problem that I and others have been having, including on 10.4.x systems):
When I attempt to repair permissions on my HD with Disk Utility, I get this specific error message: "Disk Utility internal error -- Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility" and the repair-permissions will not proceed. It fails to get the proper "correct" permissions info for that drive to allow the repair. The error log points to a file in the Library called "DiskManagementToll" The path is ~/System/Library/PrivateFrameworks/DiskManagement.framework/Resources/DiskManag ementTool)
This problem is appearing in many forums here and elsewhere, including 10.4.x systems (like mine) and persists in a few after deleting suggested files. Is there a sophisticated solution that addresses the problem through the DiskManagementTool file by replacing some values or replacing the file from a backup vis SUDO or Root?
Previous posts have focused on Macs running 10.3.x and with iTunes 6.0x installed. Not here, so the problem is more general. None of the "delete iTunes / plists / Chess.app" suggested fixes have worked for me. Also tried running DU from my Tiger install disk; no luck! -- still fails when it tries to determine the correct permissions.
The "DiskManagementTool" file apparently either stores the correct file permissions or handles reading them from the receipts in the Library. If I understand things right, Disk Utility is actually a (user)-permissioned graphic front end, while DiskManagementTool is a Root-user-level tool that actually does the heavy lifting. Can I replace -- and any benefit to that -- or rewrite it with proper access?
There is a complete crash log report in Crash Reporter, by the way. Anyone want the text, and would it help figure out what's happening?
I've tried the suggested deletion of iTunes 6.0.2 or Chess.app and their plists (these and other steps were suggested on MacFixIt at http://www.macfixit.com/article.php?story=20060111090035797 the advice is, basically, to delete iTunes 6.0.2 and/or Chess.app and related plist files.) As I said, no luck!
Everyone that I talk to says it MUST be the fault of some other 3rd-party disk utility software.
For what it's worth, I HAVE run Disk Warrior -- and, the drive that's having the problem is a recent reinstall from a backup using Carbon Copy Cloner. The original disk is NOT having such a problem, only the hard drive on my iBook after the reinstall. Don't know if that gives any clues (or to how the link gets somehow disengaged between Disk Utility and the Disk Management Tool file / software).
Any thoughts on that? What about replacing the Disk Management Tool file in the Library or forcing some kind of re-link to it? some Unix guru MUST know a fix!
Obviously, the big worry for me is that I can't update my System to 10.4.5 or anything else without repairing permissions first. This IS a big deal. And others are having the same problem. Help?!?

Answer 1

A system problem was involved that became, briefly, a "known issue" that was solved in the next minor update. Solved, anyway, by the advice given by the last poster. Thanks! SJ
