@Nishihama , This issue is caused when there is less than two unallocated sectors between logical partitions. The Extended Boot Record is stored in the unallocated sector area. In your situation the problem arises with sda5 and sda6 sda5.
332625887 end of sda5 332625888 start of sda6 The source of the crash is in the libparted library, and hence will show up with partition tools that use libparted, such as parted or gparted. This issue was also reported in upstream Debian.
