[Linphone-developers] Bug: Linphone-3 crashes when using bluetooth headset as audio device

[Xuân Baldauf]

Hello,

I'd like to use linphone as softphone using a normal bluetooth headset. However, linphone crashes when I attempt to do that.

How to reproduce

1. Start linphone-3 (compiled form linphone-3.0.0).
2. Go to View/Preferences/Multimedia Settings
3. Change "Ring device" to "PASND: bluetooth"
4. Press the Ring sound "Play" button.

Expected result

Linphone plays some sound.

Actual result

Linphone crashes.

I've repeated this using gdb and I get follow stack trace:

Program received signal SIGSEGV, Segmentation fault.

I hope that helps. :-)

ciao,
Xuân.

P.S.: It appears that all "pasnd" sound devices show the same behaviour.
