This bug occurred for me when I opened the software-center and clicked "file -> sync between computers". Nothing appeared to happen for several seconds, at which point software-center crashed. I am running 12.04 and am current on all updates.

Same for me as Ian in comment #7, except maybe I didn't have to wait as long for the crash to occur.
