The bug report doesn't show *how* to put the Samsung Galaxy S3
in "PTP" mode (which I know nothing about).

Googling "How to put samsung galaxy s3 in ptp mode", I find:

Which says:
1. Connect the phone (in that case, to the Mac)
2. Pull down the notification bar (in that case, on the Samsung phone)
3. Tap on the connection (in that case, the same USB connection)
4. Select PTP mode (to transfer photos)

When I tried that on Linux:
1. Connect the phone by USB to Centos 6 (this pops up first):
2. Pull down the notification bar (Connected as a media device):
3. Tap on the Ongoing connection:
4. Select PTP mode:
5. The Samsung Galaxy S3 is now in "Connected as a camera":

Hmmm... this pops up again, on the Desktop:

But, wait! This then shows up in the menus in a few seconds:

And, for the first time, the folders are no longer zero size:

Pensively, I click on the DCIM folder, hoilding my breath:

Voila! Success at last!
It's so simple, once you already know the answer!

PS: I'm not sure if there is a graceful way to disconnect;
and, I'm not sure if I should leave the phone in PTP mode; 
but, the good news is that single and multiple photo transfer 
by USB wire now works, in PTP mode, on the Samsung Galaxy S3!
