libgtk1.2 & libgtkxmhtml1

[Gerard Robin]

Hello,
After getting this message :
  ....
  express: Depends: libgtk1.2 (>= 1.2.6-1) but it is not going to be installed
           Depends: libgtkxmhtml1 (>= 1.0.54-1) but it is not going to be 
installed

I don't find this packages in testing.
Can someone give me a clue to find them ? 
TIA
