synergyc crashed with SIGSEGV in std::_Rb_tree_increment()

[dobey]

syngergyc keeps crashing on my laptop, a very short time after start-up. And it's not getting restarted when this happens, even though I've passed --restart to it. Presumably it's not handling the SEGV signal and restarting a new copy when it happens, which could be another bug.
