[Arthur Marsh]

Package: gnu-fdisk

When trying to identify the filesystem type on a USB mass storage device
I ran:

# gdb --args fdisk -l /dev/sr0

There appears to be no gnu-fdisk-dbg package in debian, and even after
installing libc6-dbg and libparted1.8-dbg, the backtrace is still only showing:
