Bug#474346: Installer keeps asking to insert CD1

[Frans Pop <elendil@planet.nl>]

Package: apt-cdrom-setup
Version: 1:0.34
Severity: important

This is a follow up to bugs #464023 and #470423.

I downloaded the lastest version,  weekly-builds, April 2nd. The
checksum matched.

But, the message is displayed, yet. "Insert the CD 1 ..."

I tried press ENTER, but nothing happened and the message continued.

I had to open a terminal and I typed "umount /cdrom" and after "eject".

After, I inserted the DVD again, the installation process continued 
normally.

Should I get the DVD image from lenny_di_beta1? The image was created
in march 17th.
