bluetooth-wizard crashes when the name of a discovered device is NULL

Just adding a note here that since Bluetooth is not yet officially working on the Nexus 7, I am going to wait to try and reproduce until we have an official fix. I'm a bit concerned about testing with such a workaround.

Note that the problem also occurs on Intel-based PCs, so until the bluetoothd crasher on the Nexus 7 is fixed it can be investigated on the PC platform. Probably the fix is even the same on both platforms.

Status changed to 'Confirmed' because the bug affects multiple users.

No, we can't really say it's a duplicate yet -- this bug is missing a backtrace for the crash.

Till, would you be able to reproduce the crasher (given that it's likely tied to that particular device you used not reporting a bluetooth name), and attach/paste a backtrace?

I've experienced this issue today and possibly come up with a workaround.

Ubuntu 12.10 x64. USB bluetooth dongle. Let me know if you need any further hardware info.

Initially, when scanning for devices, some sort of ID of the device was displayed (a hex UID type string). Any time I clicked on this the applet crashed and I saw the crash report for "bluetooth-wizard".

I did this a few times, but then I tried again and waited patiently whilst it continued to search for devices. Eventually the hardware ID listed changed into the name of my BT headset. Now when I click to select, and click Continue, I get no error at this point (it doesn't connect to the device in the end, but I'd wager that's a different issue).

Hope that's useful to someone.

I believe am seeing the same problem trying to pair a Microsoft Bluetooth Wireless Laser Mouse 8000 as it shows just the hw address, and if I select it, it crashes. Also interesting to note this device I believe has no PIN, though not sure if that matters.

I have attached the backtrace (hopefully I did this correctly.) If I add a Bluetooth device that has a name (such as my phone), it pairs no problem.

I should note I am seeing this on Ubuntu 12.10 x64 on a desktop pc, not the Nexus 7 as original bug was logged as.

Regarding to mloebl who provide a stacktrace of the probem(even if it is with amd64 architecture), setting the status of the report back to confirmed.

I've got a ZelHer P20 headset and a W520 Lenovo laptop, the same problem occurs.

What I observed is that during the first 60 seconds of activating the P20 headset, running bt-adapter -d will display the Name: (null) and in the bluetooth-wizard, it only shows the bt address (mac-like format).

After about 60 seconds of the headset in pairing mode, re-running bt-adapter-d, the name field is now populated. After the name field is present, pairing can be complete.

So, while clearly gnome-bluetooth should handle the case where name is null, there may be a workaround if you can keep your device in pairing mode long enough so that the name of the adapter appears.

I updated to 13.04, and I can now add the mouse that was crashing 12.10 before thru bluetooth-wizard. However, I do lose the mouse at some point (still trying to determine why it disconnects at some point, but may be unrelated to ubuntu.)

The work around it post 8 worked for me, I was having the issues everyone else was and the workaround in post 8 made it all work!

Thanks guys!
