got a 1gig object, when I get it I get a bad_alloc error.
This is on a 64bit Ubuntu 12.04.1 LTS box, with packages installed from the ceph repository.

I believe this got fixed in 234becd3447a679a919af458440bc31c8bd6b84f.
Previously it was trying to read a full object at once, which in this case would have involved asking for a 1GB memory allocation.
