Dual-head, primary on the right (i.e. Unity taskbar sits between monitors), nvidia-current binary driver, 270.41.06-0ubuntu1.

Yes, bug #778075 looks like a duplicate of this one. I often get the same crash (segfault at 318) when running Java applications. I got a stack trace from gdb that shows it crashing in g_closure_invoke ():
