Bug#649641: pulseaudio mutex issue on Alpha architecture

[Bob Tracy]

Package: pulseaudio
Version: 1.1-1
Severity: important

Iceweasel and firefox browsers crash with the following error:

Assertion 'pthread_mutex_unlock(&m->mutex) == 0' failed at pulsecore/mutex-posix.c:106, function pa_mutex_unlock(). Aborting.

Always reproducible by starting either firefox or iceweasel, then clicking
on the drop-down main menu in the upper-left corner of the browser window.
The application immediately aborts with the above error message.

See https://bugs.meego.com/show_bug.cgi?id=13567 for a similar bug report
on the ARM platform.  A workaround suggested there is to disable the PTHREAD
priority inheritance feature (in the source package) by adding

pulseaudio_cv_PTHREAD_PRIO_INHERIT=no

in "configure.ac" before

AS_IF([test "$pulseaudio_cv_PTHREAD_PRIO_INHERIT" = "yes"], [
    AC_DEFINE([HAVE_PTHREAD_PRIO_INHERIT], 1, [Have PTHREAD_PRIO_INHERIT.])
  ])

I have no idea whether this is applicable to Alpha.
