zless: >Smells a bit as some sort of bug. Try rebuilding readline?
That's what I hesitated to do in fear of blurring clues. Done. i5-64 /home/hafi # emerge -q readline >>> Verifying ebuild manifests >>> Emerging (1 of 1) sys-libs/readline-7.0_p3::gentoo >>> Installing (1 of 1) sys-libs/readline-7.0_p3::gentoo >>> Recording sys-libs/readline in "world" favorites file... !!! existing preserved libs found Hrm. Replacing the obviously corrupt preserved_libs_registry with the clean one from my backup? That would be the end of the investigation. Hartmut
