Buggy 'diskimages-helper', unable to mount a particular sparseimage
I'm working with a clean installation of 10.6.1. Nothing has been added.
The OS opens up sparseimages made by SuperDuper just fine.
However, the 'diskimages-helper' process totally fails to open an encrypted/password protected sparseimage file I've used for years. I have it on my Desktop. It was made within 10.4.11 Tiger. It works perfectly in 10.5.8 Leopard. It NEVER works in 10.6.1.
I have verified it as OK from inside Disk Utility on 10.6.1. Disk Utility reports the name of the unencrypted volume image correctly. Therefore, there is nothing wrong with my sparseimage and nothing wrote with Disk Utility's ability to read it and verify it.
The specific problem is with 'diskimages-helper'. When I attempt to Open the image via the Finder, I get the usual window where I input the sparseimage's password. The password is successful. However, no progress window ever appears and 'diskimages-helper' revs up, eating as much as 28% of my CPU, never stopping. The process will not 'Quit'. It has to be Force Quit. Once stopped, the Mac reports the failure to mount the sparseimage.
When I use the Open feature in DiskUtility, everything is the same as when opening the sparseimage via the Finder, except for the following oddities: When Disk Utility asks for the image to Open, the window actually says "Select Image to Attach". What does that mean? Attach?! I am only opening an image via the usual method. When I choose my sparseimage I get a "Disk Utility Progress" window that reads "Attach Image "etc.sparseimage", then the progress bar, 'Cancel', and 'Mounting...". The same endless 'diskimages-helper' problem results.
I have now replicated this problem across two clean installs of 10.6.1. The problem is consistent. I have verified that there is no permissions conflict. I have full read and write permissions for the sparseimage.
My logical guess is that the facility to handle encrypted sparseimage files is corrupt in the current version of 'diskimages-helper', which is part of the DiskImages.framework version 10.6.
