Bug#461735: twinkle: freezes when using a bluetooth headset both ways

[Frédéric Brière]

Package: twinkle
Version: 1:1.1-2+b2
Severity: normal

Twinkle locks up when placing a call if using a bluetooth headset (ALSA:
other device) as both speaker and microphone.  It works fine for one
role or the other, though.

Looking at the strace output, this looks like a deadlock:

  gettimeofday({1200826491, 45119}, NULL) = 0
  gettimeofday({1200826491, 46520}, NULL) = 0
  ioctl(3, FIONREAD, [0])                 = 0
  gettimeofday({1200826491, 46647}, NULL) = 0
  select(13, [3 4 6 8 12], [], [], {3, 529525}) = 1 (in [6], left {3, 360000})
  futex(0x84211ec, FUTEX_WAIT, 2, NULL)   = 0
  futex(0x84211ec, FUTEX_WAIT, 2, NULL)   = -1 EINTR (Interrupted system call)


(It's kinda sad, as twinkle is pretty much the only SIP phone that has
any support whatsoever for BT headsets.  Well, at least we're halfway
there!)
