Like it says. Specifically, diskdrake started from a root command line, single hard drive (/dev/sda). diskdrake opens with /dev/sda shown as a tab, but no partitions painted. If you toggle to expert mode, the partitions are then painted correctly.
This has broken in the same way at least twice in the past.
This does *not* happen if diskdrake is opened via MCC instead of from the command line.

screenshot of unpainted tabs
and that just happen after latest gtk+3 update...
This also doesn't happen in the install for "Custom Partition Selection"
Still valid today with drakxtools-17.88-1.mga6, so it will likely still be valid in the released Mageia 6. Thus tagging with MGA6TOO for a potential update and targeting Mageia 7.
As mentioned in comment 4, diskdrake shows the partitions properly when run embedded in the MCC. When run standalone, they don't display at first but will if you toggle expert mode.
Partitions do not paint when diskdrake opens (again) =>
Partitions do not paint when diskdrake opens in standalone mode
I still haven't been able to reproduce, but I run it over ssh so that may make a difference.
