Fable Fox here:

Yep, it crashed too. Official 2.66a build.

Win 7 / 64 bit. NVidia GT240.

As mentioned, open the nodegroup via tab, and Blender just disappear.

Fixed in r55444. This was actually caused by a buggy implementation in the Bokeh Blur node, causing unpredictable memory errors. Not entirely sure why it happened only in groups, probably the allocated memory then got placed in a position where exceeding it could do more harm. Anyway, thanks for reporting!
