When I wrote this, I did not really know much about this, I just spotted 
the 2nd slot. At that time, I also had a little libpng trouble, I could 
not update @world due to libpng blockers. I unmerged libpng, updated 
something that was blocking (don't remember what), and remerged libpng, 
because many applications were no longer working. I did the world update, 
ran lafilefixer --justfixit, emerged @preserved-libs, and had to do a 
revdep-rebuild, don't know why, I thought with FEATURES=preserve-libs this 
should no longer necessary.

But in the end, everything is sane now. My eix output looks similar, I 
also have both 1.2.43-r3 and 1.4.2 installed.

Weird. I just tried that, and thunar-1.0.2 compiles just fine.
Does /usr/lib/libpng12.so.0 exist on your system? But, wait a minute, my 
thunar links to libpng14.so.14, not to 1.2. Do you have 
/usr/lib/libpng14.so.14? Maybe lafilefixer -justfixit fixed something for 
me, and you should try this, too?
