Subject: Crash in src/gatt-client.c (was Re: setting indication on GattCharacteristic1 interface)

bluetoothd crashes when I attempt to close the connection and
reconnect through d-bus interface.

bluez @ 4d7b1d2b347423a7a79647e51b31744f3e044612

I've put the trace and btmon log here:

https://www.dropbox.com/sh/ddo9kuux9lixj4l/AAB-dWv3aZhfi27KXMMBkoHxa?dl=0

And here is the script that reliably triggers it. It is an
implementation of the Nordic Semiconductor nRF51 DFU bootloader.
Unfortunately you need appropriate nRF51 hardware to duplicate this.

If there's any more information that would be useful, please let me
know, preferably with the exact command-line to gather the
information.

Ah, never mind about this -- it was my configuration error.

It doesn't crash anymore, thanks. But it doesn't connect either:

$ ./bluetoothctl
[NEW] Controller 00:1A:7D:DA:71:13 qountdown-0 [default]
[NEW] Device CD:83:22:A3:1C:5E DfuTarg
[bluetooth]# power on
Changing power on succeeded
[CHG] Controller 00:1A:7D:DA:71:13 Powered: yes
[bluetooth]# connect CD:83:22:A3:1C:5E
Attempting to connect to CD:83:22:A3:1C:5E
Failed to connect: org.bluez.Error.Failed

The crash should now be fixed upstream, thanks for the logs.
