Comment # 19 on bug 1020034 from Stanislav Brabec

Comment 17: This is non a standard conforming CD-Extra. Standard CD-Extra
contains audio first, then data track.

Comment 18: Could you provide a cdinfo output from your pressed CD-Extra?

I cannot reproduce with my CD-Extra. Even after downgrade of libblkid1 from
Leap 42.2, "udisksctl info -b /dev/sr0" shows correct label. And even after
upgrade to Tumbleweed, blkid shows nothing.

Proposed patch looks safe and it can be added to the next update round (To save
work of Quality Assurance team, I am doing a batch update once per several
months.)

But I suspect, that your CD is not a real standard conforming CD-Extra/CD-Plus.
It will not help to fix blkid for a real CD-Extra. It would need more work.
