Problem with SMB Shares and Volume Menus

[jtk]

I've been running into an oddball issue with the volume selection menus in 2.5. When I have an SMB share mounted by root (and unreadable by users), the source and target menus are both grayed out. When the "Options" button is clicked, both the "General" and "Advanced" tabs and screens behave as expected, but the "Okay" button doesn't seem to do anything. Deleting the settings or preferences doesn't fix the problem, but dismounting the SMB share does.

I suspect that the same thing might happen if any volume that SD! doesn't have read/execute privileges on is mounted. Unfortunately, I haven't had an opportunity to verify that scenario.

System info:
PM G5 dual 2GHz w/ 4GB
10.5.5
Two internal drives (desired SD! source and target volumes)
External FW drive (Time Machine volume)
Drobo/DroboShare (SMB share)

I just mounted a read-only iDisk volume and SD! seems fine, jtk. Try removing the "saved settings" folder in your Library/Application Support/SuperDuper! folder and repeat the test.

The problem doesn't occur (as you verified) with read-only volumes, only when the current user has no permissions (e.g. a volume mounted by root with 700 permissions) — neither read, write, nor execute. And, as I said, deleting the settings (okay, I didn't specifically say saved settings...) doesn't have any effect.

Also, I'm not sure whether this problem will occur with locally connected volumes, or only with network shares. I can reliably duplicate this with SMB shares, but haven't tested it with AFS or NFS volumes. Might be interesting to try, if a way can be found to keep them from getting unmounted when the root user logs out.

Just guessing here, but it looks to me like this has something to do with the way SD! or Cocoa handles the list of available volumes.

Do you get any errors in the console/system logs?

Indeed.

From the console (identical info is system.log):

Yes, indeed: the system call we're using to retrieve the list of volumes is throwing an exception. OK, thanks.
