I have this problem in 12.10 and the same bug happens regardless of whether I try to browse the files on device via blueman, or the lame bluetooth-applet which has unfortunately become the default bluetooth app in 12.10.

Whereas on another laptop which is EXACTLY THE SAME MODEL (Samsung NP900X4C) as this one, I installed 12.04 and Bluetooth works like a dream. 2 mins after install, I was able to link to my phone via Bluetooth and immediately set up the internet connection via the phone, all using a simple wizard. I am really regretting going for 12.10 on the first laptop, it has brought a lot of trouble compared to 12.04.

For anyone who is suffering while waiting for this bug to be fixed, there is a workaround at: http://askubuntu.com/questions/214635/bluetooth-cant-browse-files-in-ubuntu-12-10/235517#235517

Software: Gentoo ~amd64, Gnome 3.6, G-bluetooth 3.6.1, gvfs 1.14.2, obexd 0.46,
0.4.6, bluez 4.101

To reproduce: try to browse a cell phone via bt menu on G-shell top bar.

Reproducible 100%

Downgrade gvfs up to 1.12.3 fixes the problem.

Reproducible: Always

We need a gdb backtrace to determine what caused the crash.

Please re-emerge gvfs, glib, bluez, dbus, and dbus-glib with "-ggdb" in CFLAGS and "splitdebug" in FEATURES (see http://www.gentoo.org/proj/en/qa/backtraces.xml for more details).

Then emerge app-admin/abrt (if you don't have it already), do /etc/init.d/abrt start, do whatever needs to be done to crash gvfsd-obexftp, obtain the backtrace from abrt-gui, and attach it here.
