Comment 6 for bug 617885

Attaching a trace.

This is not related to sudo. I get the exact same trace when using gksu[1].

It seems that it might be crashing while recognizing filesystems during disk scan.
The crash is in GParted::GParted_Core::get_filesystem.

I get the crash with the following root-on lvm2 situation (exporting some unneeded vgs did not alleviate the situation) [2 see below]:

I was able to get a trace by doing:

bash$ apt-get source --compile gparted
bash$ cd gparted-0.6.2/src
bash$ sudo gdb ./gpartedbin
(gdb) break main
(gdb) run
(gdb) catch throw
(gdb) c
...
(gdb) bt full

Detailed output attached

[1] after using 'sudo passwd' to set a root passwd... that is another bug
