     Seems to me there's something weird, both, in libreoffice depending 
on just one single version of libstdc++, and in libklabxml being broken 
by this version of libstdc++, be it the fault of kde or libstdc++ 
developpers.


     The dependency chains might be shortened by linking at least part 
of the libraries statically. All this dependency buysiness mostly comes 
from the abuse of dynamic linking. The only real advantage of dynamic 
linking is faster upgrade in a distribution, but it often turns out to 
make it just impossible.


     As a simple rule, I don't understand why Debian accepts a package 
which depends on just one version of libstdc++, therefore de facto 
preventing any upgrade. To be accepted, this package should be linked 
against a static version of libstdc++6, hence dropping the dependency. 
But, Ok, it's Debian's buziness for now.
