Bluetooth "Browse files on" functionality broken

[Gioele Barabucci]

It is not possible to browse files on bluetooth devides using the `gnome-bluetooth` "Browse files on...".

This is a regression from Karmic where the "Browse file on" functionality was flawlessly working.

Steps to reproduce, TEST CASE:

1) enable bluetooth on mobile device;
2) select "Browse files on" from `gnome-bluetooth` applet;
3) select one mobile device;
4) wait for the nautilus window to appear (it will not).

Tested on a brand new Lucid LTS 10.04.3.

As suggested in bug #542805 (closed as fix released but only partially really fixed), I tried running `/usr/share/doc/obexd-client/examples/list-folders`. This little application crashes with

----

Bug #283064, comment 22 (bug closed as invalid) suggests that this problem is caused by a mismatching version of `obex-data-server` and offers a PPA (currently outdated) to solve this problem.

Bug #161 on obex-data-server's mantis (http://bugs.muiline.com/view.php?id=161) from 2009 says that changing the obex-data-server DBus config fixes this problems. They also applied a patch to their SVN version.

Could you please fix this bug by backporting to Lucid versions of gnome-bluetooth and obex-data-server that are compatible with each other? Thank you.

I see the same bug in Ubuntu 11.04 (Natty)!

The mentioned Traceback of the example script "list-folders" shows more hints now:

I have same issue with 11.10 (upgraded from 11.04 - not clean install), but it had worked fine for me on 11.04.

[Steve White (stevan-white)]

Ditto freezeloud. This is on a Samsung NC-20.

[Steve White (stevan-white)]

Maybe related:
When I pull down "Browse files on device..." from the bluetooth applet, the dialog is mangles: the list of devices is very very short, one can just barely see some letters.

See attached.

The scroll buttons kind of work, but barely. So I saw the device in the list and was able to select it.
Then I clicked Browse.

The bluetooth applet crashed, and disappeared from the gnome panel. In /var/log/messages
 at-spi-registry[12731]: segfault at c ip 00d4fb99 sp bfc881a0 error 4 in libgconf-2.so.4.1.5[d3a000+2c000]

[Steve White (stevan-white)]

The dialog:

[Steve White (stevan-white)]

Same problem on an x86-64 desktop, for which Bluetooth file browsing was also working previous to an upgrade from 11.4 to 11.10.

[Steve White (stevan-white)]

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!)

Here's a backtrace.

It will be better, when somebody tells us the secret of where the libgnome-bluetooth debug symbols are hidden.

This is looking like user-interface code to me.

I had no problem with this on 11.04. On 11.10 I see above mentioned problems #4 + #8.

[Tuomas Lähteenmäki (lahtis)]

why do not you fix this Lucid 10.04 version Although this would have to be a long-publishing support.

Man this is why Linux is NOT meant for desktop machines.. if you want X powered system ppl should go OS X, things there work flawlesly.. Me to ended up with faulty system with no browse bluetooth no more... Oneiric Oncelot

[Steve White (stevan-white)]

Hey guys!

This is pretty bad for us Bluetooth users.
Please take some action!

[Oliver Joos (oliver-joos)]

@Steve: Yes, this is a major bug! To help solving it, we should be as precise as possible. I suppose you talk of several problems in your comments: browsing fails, gui problems, seg faults. Gioele, Thomas and I all see a "DBusException". If you see other symptoms then please open new reports for them so that the right people hear of them as soon as possible.

My bug 839157 is probably the same as this. But I resist from marking it as duplicate because of the multiple symptoms mentioned here.

[Steve White (stevan-white)]

Hi Oliver!

I don't doubt this is a cluster of bugs. I just reported what I see, trying to do a task that used to be easy.

It is difficult to be precise about a pile of bugs.

If you could, say, fix the basic functionality (not the device dialog issue), and push those fixes out, maybe clarity would improve.

In fact, other bluetooth-related bugs showed up in the last release, but I'm hesitant to report them, because it has been such a mess.

We are anticipating hearing from you!

[Oliver Joos (oliver-joos)]

Unfortunately am just an affected user like you. I did not look into the source of bluetoothd yet. But I made positive experiences by splitting up bugs into one report per symptom. Anyway thanks for sharing your findings!

[Tuomas Lähteenmäki (lahtis)]

im fix it this proplem a removed A-link usb-card and add a Lacie pci-card same place. Maybe usb-card is broken or else.??
This is very hard find.

Please check my usb bug 918772 (https://bugs.launchpad.net/libusb/+bug/918772) there are call trace.

[Oliver Joos (oliver-joos)]

I found a workaround for the similar bug 839157 - see my comment 30 there for details.

If you feel affected by this bug and are able to "fix" it by that workaround then please share your findings and leave a comment here!

Please also note that the Ubuntu 10.04 live-cd version software, however, will work correct. But when you installed and updated software. Software not working. What has be changed?
