From the y2log, I picked up the following logs:

>From the above log, we could see that /dev/sda4 is deleted in line 9343 and the
result of dumpObjectList in line 9349 contains 'deleted' compared to line 1043.
I think it's the reason why `vgremove` command failed.

So users should avoid deleting partitions that are being used. It would be much
better for yast2 to check the partition if it's being used before could be
deleted.
