Segfault on audio pairing

Segfault on audio pairing

[Florian Sievert]

Hi all,

I run into an issue with bluetooth when trying to connect to an audio
speaker on my Fedora 26 system. I was able to reproduce this at least on
two other Fedora systems with different hardware and thus opened up an
issue in redhat's bugzilla:

https://bugzilla.redhat.com/show_bug.cgi?id=1469961

While performing a discussion on the fedora user mailing list, some guy
confirmed the issue as well and pointed out that some similiar Arch
Linux does exist:

https://bugs.archlinux.org/task/53442

I was pointed to this mailing list to raise the issue and asking for
further advisory on debugging this segfault. The issue is 100%
reproducable here on my system and seems just to occur when connecting
an audio speaker via bluetooth to the system. All other bluetooth
devices seems to be working fine. Some logs and the segfault are
attached to the redhat issue. So how may I help to narrow down this
segfault?

Many thanks in advance,
Florian

There have been at least one fix related to some headset that are using GATT:

Florian,

I can add that it fixes a crash that I have been observing with Sony
MDR-1000X and possibly also with Sony SBH52.

It might be a good idea to compile a list of affected headsets so we
can probably add to the changelog when releasing.

Good idea. From my side:

1) Sony MDR-1000X
2) Sony SBH52

There was also a report from Per who used a Plantronics headset however
I'm not sure what is the status with the above patch applied.
