Yet in Thunar, right-click Properties shows these as
704.0 KB (720,896 Bytes)
64.0KB (65,536 Bytes)

Turns out that JPG sizes are all reported as even multiples of 64K, 
although the size reported isn't proportional to the real size.

A few TIFs in the same directory all show the right size.

Didn't find anything in the xfce bugzilla, but I may not have been 
searching in the right spot.
