how to deal with BusyBox and apport-collect

[∅]

On this bug:
https://bugs.launchpad.net/bugs/1380774
and bugs like it in debian-installer, the shell is BusyBox. Being a
limited shell, there's no way to perform normal apport/ubuntu-bug
functions. In this case, and especially with this particular one where
a crash doesn't happen so much as a simple failure, what information
should be collected to make the bug report complete?
