The new libc6 package (2.1.2-12) is causing some dependency problems. It conflicts with libc6-bin which is required by some other packages, causing their removal (when using dselect, at least).
I've checked, and no bugs are open against these packages (e.g.: w3m; the latest netscape-base-4) requesting the removal of the libc6-bin dependency. It appears that either the libc6 package should be fixed, or severity "important" bugs should be filled against all packages depending on libc6-bin... -- "One disk to rule them all, One disk to find them.
