segfault in bluetoothd

[Florian Hars]

Binary package hint: bluez

I tried to use a bluetooth dongle to transfer some files from my phone (which worked on another computer and gutsy or hardy, don't remember which), and one result I got was:

[ 5014.824039] usb 5-1: new full speed USB device using uhci_hcd and address 2
[ 5015.264163] usb 5-1: configuration #1 chosen from 1 choice
[ 5015.325106] Bluetooth: Generic Bluetooth USB driver ver 0.3
[ 5015.325601] usbcore: registered new interface driver btusb
[ 5268.841743] bluetoothd[2620]: segfault at 656c6966 ip 656c6966 sp bfb29cbc error 4 in gconv-modules.cache[b7be3000+7000]

I have not found a way to reproduce this, but bluetooth still doesn't work, I can (partially) browse the files on the phone, but have not managed to transfer even one file, most of the time the file manager just closes without any error message whatsoever when opening a folder, sometimes it says "not connected" when trying to open a file.

One error I got which may be related (but which is not reproducible) was:

Just after installing bluetooth dongle:
Bus 005 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

When I try to explore my phone through bluetooth nautilus suddenly closes and in the log it says:

kernel: [ 766.094836] nautilus[6197]: segfault at 0 ip b78ff3d7 sp bfd37014 error 4 in libglib-2.0.so.0.2000.1[b78a2000+b6000]

Very annoying to have latest ubuntu version and not being able to explore a normal mobile phone.
