Bug 302003 – skype aborts because emul-linux-x86-soundlibs installs pulseaudio 32bit libs regardless of wether pulseaudio is installed

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Marcel Partap 2010-01-24 03:57:20 UTC]

well skype seems to try and load pulseaudio 32 bit libs, which are contained in the emul libs pkg. but i do not have any other bits of pulseaudio -> mysterious assertion in pa_mutex_unlock().

Reproducible: Always

Steps to Reproduce:
after upgrading the emul-packages, skype would always abort with
Assertion 'pthread_mutex_unlock(&m->mutex) == 0' failed at pulsecore/mutex-posix.c:108, function pa_mutex_unlock(). Aborting.

Actual Results:  
assertion

Expected Results:  
no assertion in pulseaudio compability libs because of missing native lib?

i was clueless how to fix it but http://share.skype.com/sites/linux/2009/09/some_explanations.html#comment-150551 gave the most helpful hint to just
sudo chmod o-r /usr/lib32/libpulsecommon-0.9.19.so /usr/lib32/libpulse.so.0.12.0 /usr/lib32/libpulse-simple.so.0.0.3
which fixes the problem, but in a stupid way.

wow WTF? bugzilla is asking all these questions and ommitting them when displaying the bug report? gross misconfiguration, anyone?
just in case they'd else be lost:

What skype version do you have installed? I will probably add a USE flag for installing pulse libs or not, rdepending on pulseaudio when installed

(seems that skype autodetection should be improved a bit or, at least, it should fallback to alsa if pulse fails, but it looks more like an upstream problem)

[Comment 4 Marcel Partap 2010-01-24 17:53:23 UTC]

both 2.1.0.47 and 2.1.0.81 have the problem, and yes upstream should apply some sanity checks before depending on an optional library... ^^
