-- Information about the crash:
I use qemu-nbd to connect a raw file to /dev/nbd0. Then when I use KDE partion
manager to modify partion tabe, Dolphin crashed.
Before this time, it also crashed when using KDE partion manager to create
volume system on the same device

The crash can be reproduced sometimes.
