iPhoto why so suddenly crash?

Did some recent software update break iPhoto completely? What gives?

I've been doing some testing of iPhoto Library Manager merge functions using two small 20 image test Libraries. These are both new, very generic Libraries. I've crashed iPhoto at least six times doing basic manipulations of these test images. I'm not talking merges, I mean editing album names, adding comments, etc.

Weird.

Update 2/18/08: If this turns out to be a persistent problem on 10.4 but not 10.5, the suspicious among us will start suspiciousing ....
