Crash caused by too many open file descriptors (cancellables, dee model sockets), and that is because there is currently now way to detect if search channel should be closed. This fix: https://bugs.launchpad.net/unity-scope-home/+bug/1228260 will reduce number of fds a bit, but it doesn't fix the root problem. A fix in libunity is needed to detect dead channels.
