The problem disappears when I revert the libdb-dev build dependency to libdb4.6-dev. (debs are in my PPA if you want to test).

A proper fix would be to sort this db 4.6/4.7 mess. ** Attachment added: "cyrus-sasl2_2.1.22.dfsg1-23ubuntu2--2.1.22.dfsg1-23ubuntu3.debdiff" http://launchpadlibrarian.net/21860494/cyrus-sasl2_2.1.22.dfsg1-23ubuntu2--2.1.22.dfsg1-23ubuntu3.debdiff -- sasl2-bin broken, segfaulting during install https://bugs.launchpad.net/bugs/323409 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
