Title:
  Bazaar crashes when adding a files larger than 4GB

Status in Bazaar Version Control System:
  New
Status in “bzr” package in Ubuntu:
  New

Bug description:
  Wanted to see if how well Bazaar supported large (multi-gigabyte)
  files. Looks like the state file doesn't support sizes that can't be
  represented in 32 bits.

  Arguably storing files larger than 4GB in a distributed version
  control system is probably not the best idea, but there are
  occasionally cases like VM images or other large binary assets that
  might hit this limit. At very least a "Sorry. Too big" error would be
  nice.

  Steps to reproduce:
      mkdir /tmp/large
      cd /tmp/large
      bzr init .
      dd if=/dev/zero of=large.dat bs=1000 count=5000000
      bzr commit -m "Large file"
