1. STEPS TO REPRODUCE
=====================

# create 4G sparse empty in tmp, and register as loop0
dd of=/tmp/blocks bs=1M count=0 seek=4096
sudo losetup -f /tmp/blocks

# use gparted without problems on the single block dev
sudo ./src/gpartedbin /dev/loop0 # no problem

# create an empty MSDOS partition table (device label)
sudo ./src/gpartedbin /dev/loop0 # no problem

# create any primary partition of any known type, and
# refresh (CTRL+R) or restart
sudo ./src/gpartedbin /dev/loop0 # no problem

# create any partition of type 'unformatted' (raw) and
# after applying it in gparted window, the refresh
# immediately bails out with the reported stack trace
sudo gdb --args ./src/gpartedbin /dev/loop0
(gdb) break main
(gdb) run
(gdb) break abort
(gdb) break exit
(gdb) catch throw
(gdb) run
# create the raw partition and apply, after 'ok'
# (close?) gparted crashes on refreshing devices

(gdb) bt # (see comment #6)

# remove the raw partition (using fdisk, dd etc)
sudo ./src/gpartedbin /dev/loop0 # no problem

2. MITIGATING STEPS
===================
Seeing as the crash occurs in a conditional block
active only when BTRFS_SUPPORT is enabled, I thought
about

./configure --disable-btrfs
./make -s
sudo ./src/gpartedbin 

Lo and behold: problem gone. Other problems may still lurk, see my patch on
