Did you have something unusual? RAID? LVM?

I will create a new Mga5 vm and upgrade it to see if it is reproducible.
Comment 3 Nic Baxter 2016-01-16 04:11:46 CET 
I create a new vm from Mageia-5-x86_64-DVD.iso and updated to latest. Then did upgrade to cauldron. Report reproduced. Anything else I can check?

Comment 4 Nic Baxter 2016-01-16 08:35:27 CET 
just to make it more interesting. I added another drive to the vm and restartec. Running mcc then manage local disks works. I partitioned and formatted the new drive. drakdisk in terminal gives the same get children error. 

Any idea what might be happening. I thought they were the same command just launched differently.

I then shutdown the vm, removed the extra drive and restarted. Now mcc and drakdisk both fail again with the 'get children error'
