"Some import operations were not performed" from camera import

Question

Greetings,
I've been using LR3 for some time and have never had a problem importing before but starting last week (it worked fine on Tuesday, but failed starting Thursday), attempting to import directly from my Canon 7D has been producing this error dialog:
Importing directly into LR3 has worked with this camera since I got it a year ago so this problem is completely new to me.
I can import directly from the camera with Canon's utility, with Image Capture, and with iPhoto so nothing is wrong with the camera or the usb connection.
After impoting the photos from the camera to a folder on the computer with something other than LR3, I can then import those photos into LR from the disk without problems so nothing is wrong with the photo files themselves.
I have tried formatting the CF card, restarting LR3, and rebooting the computer.  Nothing has helped.
Not being able to import directly into LR3 is a pain, and one that I would like to go away.  Help?
Thanks!
LR 3.6; OS X 10.6.8; intel iMac
Additional information:  I just tried importing from the same camera with LR3 on my MBP and there were no problems so whatever is happening is unique to the instance of LR3 installed on my iMac.

If it is an ordinary folder, then you can use FInder.  Click on the folder in question and they press Command-i to bring up the info window for that folder.  At the bottom you should see a section labeled "Saring & Permissions" where you will see and have the ability to change what privigles various users and groups have with respect to that folder.  Make sure that you can write to it (on the line with your user name it should say "Read & Write", it it doesn't then change it to say that).
If however (as in my case) the issue is with a device file then the solution may be more complicated.  But since you don't mention an external drive I suspect that this isn't the case.
