Yeap.
As far as I know, amd64 architecture switches on-the-fly to i386, but once
you are there all the execution should remain 32 bits.
That is why some 32 bit applications can run perfectly on amd64, just stuff
everything on the ELF executable, including all dynamic libraries and you
are done.
If you want to stay modular and use the dynamic linking process, you should
feed all the 32 bits libs the app will ever need.
It seems libgail.so is not part (yet?) of the ia32-libs, though.

Best, Nico
