I just did a Hoary->Breezy upgrade and I did not get this question. Technically,
this file is a conffile in both Hoary and Breezy, so you should only get the
question if you manually modified the file.

That's the current one, right.

Scott, this seems to be one of the "hotplug scripts are not called" bugs we
talked about yesterday. Could this be a fallout from #15240?

This is a completely different bug (in the spca5xx kernel driver), see #15809.

libsane has got nothing to do with the spca5xx driver; however, you can
downgrade libsane by downloading

http://archive.ubuntu.com/ubuntu/pool/main/s/sane-backends/libsane_1.0.15-9ubuntu5_i386.deb

and installing it with "sudo dpkg -i libsane_1.0.15-9ubuntu5_i386.deb. However,
I hope that we can fix the hotplug script calling soon.
