picard can't find /dev/cdrom

[David Huggins-Daines]

The first time you launch picard, if you click on "CD Lookup", it will say "/dev/cdrom not found" or something to that effect.

After selecting "Options..." from the Options menu and clicking on "CD Lookup", it shows /dev/sr0 as the default device. From this point on CD Lookup finds the CD-ROM device, with no other action required.

This is not a serious problem but is kind of silly, it should get the device right from the beginning.

Status changed to 'Confirmed' because the bug affects multiple users.

Picard uses libdiscid to get the default device, which previously expected `/dev/cdrom` to be available on Linux.

Starting with libdiscid 0.6.0 it checks `/proc/sys/dev/cdrom/info` to find the first CD drive.

Note that Saucy still ships libdiscid 0.5.1, but you can upgrade using the MusicBrainz Stable PPA:
