Comment 11 for bug 822275

Tried re-installs

sudo apt-get install --reinstall bluez bluez-alsa bluez-cups bluez-gstreamer bluez-utils
sudo apt-get install --reinstall libgnome-bluetooth8 pulseaudio-module-bluetooth

No luck.
------------------------
Tried backing up /var/lib/bluetooth/, deleting its contents, re-starting.
Then I paired with my phone, apparently successfully.

The phone does *not* appear in the gnome-bluetooth applet pop-down menu, as it did before.
It does appear in the mangled Browse Files dialog, as I described in the posting yesterday.

Attempted to Browse, as in that posting, and the bluetooth-applet segfaulted, as before.

So it's not the config files, and it's not the /var/lib files.

Oh. lsusb on the Samsung laptop shows

The desktop computer uses a dongle. lsusb shows several bluetooth devices attached (not sharing files!)
