adept crashes because it can't ask to keep a configuration file or to use a newer version

Binary package hint: adept-updater

This bug probably deserves high priority, as it breaks the updating mechanism and leaves novice users with a broken system, that may not even boot.

Today I used adept_updater to get some new updates. One of these updates wanted to install a new version of the configuration file `/etc/default/linux-restricted-modules-common'. Adept crashed due to an error that would break a package or something. Then I opened Konsole and did an `aptitude upgrade`. I got the message "dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.". So I entered 'dpkg --configure -a' and it came up with the text below:

 The default action is to keep your current version.

I think I know what the problem is. Because the Nvidia binary driver in the repository's is version 100.14.11, I manually installed version 100.14.19. During installation I needed to edit the file '/etc/default/linux-restricted-modules-common' to add the modules `nv` and `nvidia_new` to the blacklist.

The bug is that adept crashes in stead of asking me whether I want to keep the old file or replace it with the maintainers version.
By the way, I chose to replace mine with the maintainer's version, as I will need to recompile the Nvidia-driver for my new kernel. I can then add those two modules to the blacklist again.
