No special libraries - just what was installed with Fedora 16.  No remote filesystems. 
There are no raw image files in this folder.

The directory with the problem is named '2011-06'.  I moved the first 140 files from 
'2011-06' to a separate folder 'save', and the remainder of the images in '2011-06' loaded 
fast.  And those in 'save' also loaded fast.

I then moved batches of 10 images from 'save' back to '2011-06'.  After 3 batches, the 
problem returned to '2011-06'.  I then moved the last batch from '2011-06' back to 'save', 
and moved them one at a time from 'save' to '2011-06'.  I found a single image, 
'g6162725.jpg', that caused the problem in '2011-06'.  There is nothing special that I can 
see about this image file.  However, this may be a clue:
