libxmlrpc-c3 prior to version 1.07 does not support 64-bit integer values. As mentioned by the OP, this is essential for rutorrent and probably other rtorrent front-ends, otherwise the reported file sizes are incorrect (truncated to signed 32-bit integers, see bug #563075)
The version of libxmlrpc-c3 available in [experimental] is actually 'stable' in upstream terminology. They have a rather strange release naming, with 'super stable' (available in Debian stable/testing/unstable repositories) being an extremely outdated version. Re-compiled rtorrent with libxmlrpc-c3[-dev] from [experimental] works fine and fixes the aforementioned bug. To sum it up, libxmlrpc-c3 1.16 from [experimental] is stable. It adds support for 64-bit integers which is essential for some software. It should at least be moved to [unstable]. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
