I can replicate the same problem here.   The thumbnails in gimp do not 
work.   Re-saving the jpeg file did produce the thumbnail in gimp. 

The preview function in konqueror does not work either.   And scanning 
in kooka in jpeg format does not produce any output.   I did the same 
test with xsane and it worked just fine.  

This is interesting....  Needs further investigation.
