[Bug 1199715] Re: unity-scope-home crashed with signal 5 in g_wakeup_new()

 

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.
