udisks2 not enumerating multiple CD burners correctly

[StoatWblr]

This is a long-standing bug in the upstream code which is tickled by corner cases (Multiple identical Optiarc CD/DVD burners and K3b)

If there are multiple CD burners installed and if they abuse the serial number field, then udisks2 and earlier software isn't picking them up correctly.

In this system there are 3 burners. Note how it's reporting sr0 and sr1

$ udisksctl status
MODEL REVISION SERIAL DEVICE
--------------------------------------------------------------------------
SAMSUNG SSD 830 Series CXM03B1Q S0WKNEAC7XXXXX sda
Samsung SSD 840 Series DXT07B0Q S14LNEAD1XXXXX sdb
Optiarc DVD RW AD-7203S 1.09 Optiarc_DVD_RW_AD-7203S sr0 sr1
Optiarc DVD RW AD-7173S 1-00 Optiarc_DVD_RW_AD-7173S sr2

_most_ packages still see 3 drives, however k3b finds itself confused because it's only looking at udi = '/org/freedesktop/UDisks2/drives/' instead of also also checking '/org/freedesktop/UDisks2/block_devices/'

See K3b bug 337553 - https://bugs.kde.org/show_bug.cgi?id=337553

you might want to report that bug upstream on http://bugs.freedesktop.org/

Just to follow-up; Have you reported the problem upstream? Do you have a ticket number?
