[Mageia-discuss] partitioning bug

Cfdisk is very unhappy about something.  

    FATAL ERROR: Bad primary partition 3: Partition begins after end-of-disk
    Press any key to exit cfdisk

It looks like cfdisk's error message is wrong.  Partition 3 is mounted 
and in use.  

Unfortunately I don't know which software to blame, but something has 
made my hard drive "interesting".  It could be; cfdisk itself, the 
Mageia 2 installer (the main suspect), the Ubuntu installer, fdisk, 
or sfdisk.  There might be multiple bugs.  

I think that the order of events was; 
I noticed a tiny amount of unused space at the end of my HDD 
the perfect place for a LiLo map file.  
Created a new primary partition (numbered 3, because 1, 2 and 4 existed).  
"Fixed" the partition order with fdisk.  
Found that the extended partition had grown to cover the whole disk. 
Found that the third primary partition had been changed to logical.  
(There were still two primary partitions in the middle of the disk.)  
Found that sfdisk has decent man pages.  
Fixed the problem.  
Found that cfdisk is still not happy.  

Does anyone know what to raise that bug report against?
