The first error: "Cannot load media" happens when wodim is invoked as a
regular user that is a member of the cdrom group, so permissions should
not be a problem.
The second error: "Cannot init drive" happens when wodim is invoked as
root.
Using or not using the -dummy option doesn't make a difference.
The hardware: Philips CDD2600 CD burner connected to an Adaptec 1542CF
SCSI controller. All the devices are recognized correctly. Inserting
a good data CD in the drive generates the event and the contents can be
opened in a new window.
First, here's the output of the regular user invocation:

A similar command line works for me (non-root, cdrom group, random LG USB
DVD burner), so this bug certainly doesn't "render the package unusable".
Downgrading the severity to non-release-critical so it doesn't block
the release of Debian 5.
