i can't be sure that the hung ssh sessions were the issue, but i can tell you that it's spontaneously crashed on more than one occasion (though this is the only backtrace i have).  in both cases however, konsole crashed when i was on a different desktop working in a completely unrelated window (i *think* it was konqueror in both cases):
