bluetoothd crashed with SIGSEGV in uuid_cmp()

[Dereck Wonnacott]

I got this apport crash when i booted my computer. I have been having a LOT of BT issues this past week from not being able to pair, applet crashes, kernel panics, you name it!

it all started when i tried to pair to a cellphone to get photos from it, the system froze with a flashing caps lock LED and I;ve had an unstable system ever since.

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

[Konrad Zapałowicz (kzapalowicz)]

This is reported against an old version of Ubuntu and many things has changed since then. Because of that we won't fix this issue however if this behavior repeats on a modern version please fill a bug report against it and we will take it from there.
