FWIW, it also crashes on a 64-bit Mac OS X system with version 6.0.3.

In[1]:= $Version

Out[1]= "6.0 for Mac OS X x86 (64-bit) (May 21, 2008)"

In[2]:= tb = Table[Exp[-x^2 - y^2], {x, 0, 2, .1}, {y, 0, 2, .1}];
Export["tb.png", tb, {"PNG", "Data"}]

During evaluation of In[2]:= LinkObject::linkd: Unable to communicate \
with closed link \
LinkObject[/Applications/Mathematica.app/SystemFiles/Converters/\
Binaries/MacOSX-x86-64/PNG.exe,7,7]. >>

Out[3]= $Failed

In[4]:= ByteCount[tb]

Out[4]= 3648

In[5]:=  Export["tb.png", Round[255 tb], {"PNG", "Data"}]

Out[5]= "tb.png"
