Cannot import photos or browse directories Canon 20D

[mmalmeida]

I have a Canon 20D and in 12.04 I stopped being able to browse or import photos.

I've tried connecting the camera via usb (normal, not PTP, mode) on 3 computers:

- Laptop 1 with Ubuntu 12.04
- Laptop 2 with Ubuntu 12.04
- Desktop with Ubuntu 10.10

On both Ubuntu 12.04 machines, in Nautilus:
1) I can open the [Camera]/DCIM directory;
2) When I try to open a xxxCanon directory the computer will stop responding, hard drive will start to be hammered and will stay like that for a long time (one hour or so) or until I plug the camera off

On my 10.10 desktop machine I can import the pictures from the exact same camera and usb cable. It's imports without any problems or hickups.

How can I help you guys figure this out? It's a blocker bug for using the computer with the camera.

I also posted on https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/995886 which I considered to be very similar to my problem.
