recoll needs a binNMU to get rebuilt against xapian-core 1.0.1-1 because the shlib version has increased - the shared library package is now libxapian15 not libxapian13. According to buildd.d.o, xapian-core 1.0.1-1 is already built and installed for all architectures: http://buildd.debian.org/pkg.cgi?maint=olly%40survex.com Cheers, Olly
