I've built an i386 testing mini.iso containing a proposed fix for this bug,
and uploaded it to:
http://people.debian.org/~mpalmer/614884_mini.iso
If someone can test it out with an NM package that has the appropriate
script (Ben Armstrong felt that an appropriate NM package wasn't already in
the archive) and let me know that it works, I'll commence the process of
uploading.
