Attempting to copy any data CD/DVD to an image file using brasero without
brasero-cdrkit presents the following options:

"Cue image" (brasero.cue)
"Cdrdao image" (brasero.toc)

No choices for image type appear when the disc is a DVD, all buttons except
"Cancel" are disabled.

After installing brasero-cdrkit, copying a data CD:

"ISO9660 image" (brasero.iso)
"Readcd/Readom image" (brasero.toc)
"Cue image" (brasero.cue)
"Cdrdao image" (brasero.toc)

And for a DVD, no choices are present but the default image file name is
brasero.iso and it does create an ISO9660 copy.

I was able to demonstrate the same behavior building upstream with --disable-
cdrtools --disable-cdrkit.

If this is the expected behavior, some text explaining that brasero-cdrkit is
required to create ISO9660 images in either package's description would help.
As the package descriptions stand I believed I had all packages required.

Version of cdrdao:
