Control: tags -1 + confirmed Hello!
The libgdk-pixbuf2.0-dev has no Multi-Arch field because neither 'same' nor 'foreign' seems to be suitable (for the current situation). As the bug submitter already mention you want the 'same' arch of the -dev as the library package itself to get the relevant .so symlinks, but it is not possible to mark the package Multi-Arch: same as there are conflicting files, eg. /usr/bin/gdk-pixbuf-csource et.al. See: https://packages.debian.org/sid/i386/libgdk-pixbuf2.0-dev/filelist https://packages.debian.org/sid/amd64/libgdk-pixbuf2.0-dev/filelist To multi-archify the -dev package a new package split would be needed. Patches welcome. Regards, Andreas Henriksson
