MASTER: do_remove BrokenCount assertion can fail

I fixed this for another code path, but apparently not for this one. Thanks. This will be a bit more complicated ...

As far as I can tell by divination from the packages that are being upgraded in these logs, most of the reports of this are from users of Xubuntu Feisty Herd 2 (they all seem to have python-exo installed, for example, and the versions are consistent with Herd 2). I'm grabbing that image from the archives now and will see if I can reproduce it from that.

ubiquity (1.4.5) feisty; urgency=low

  * Handle migration-assistant/failed-unmount being asked from ma-apply.
  * If installing or removing packages fails, then display a helpful error
    message and try to continue rather than crashing; furthermore, avoid
    installing language packs or removing packages when there are broken
    packages on the target system (LP: #54282, #69470, #80938).
  * Don't crash if Install exits due to SIGINT, SIGTERM, or SIGKILL, since
    these are probably user-generated.
  * Prepare for partman-partitioning/confirm_resize being asked during
    autopartitioning (partman-auto 62ubuntu9).
  * Do a better job of trying to get the exit code of subsidiary processes.
  * Update translations from Rosetta.
  * Automatic update of included source packages: hw-detect 1.45ubuntu3,
    migration-assistant 0.4.3, partman-auto 62ubuntu9, partman-base
    105ubuntu2, user-setup 1.8ubuntu3.
