compiz.real crashed with SIGSEGV

[Podengo]

Binary package hint: compiz

I had downloaded and installed the newest ubuntu updates this morning 4/3.
I worked fine for a few hours on my laptop, a dell 1720 wuxga with nvidia graphics
I was using Amaya (not the ubuntu package but the newsest), which I always use.
But I had recently changed the appearance preferences to maximal visual effects.
I couldnt get a window title par up to the top of the scren with all the others, and I tried the alt key, too. I was just typing and 'eventing', I guess, in the window manager. and much freezing. I could move he mouse cursor, but no clicks seemed to work, ..
