Hmm... I think that you should forget that test. I thought
that aptitude-run-state-bundle would only depend on files from
aptitude-segv.bundle, but it still reads some other files from
/var/lib according to strace. And now I get

--- Upgradable Packages (65)

instead of

--- Upgradable Packages (61)

Since the crashes are very sensitive to the system status, the
above test might not be reliable.
