[Pkg-pulseaudio-devel] Bug#550400: pulseaudio-utils: Iceweasel segfault if padsp wrapper is used

[Dominique Brazziel]

Package: pulseaudio-utils
Version: 0.9.15-4.1
Severity: normal
Tags: patch

    If '/etc/iceweasel/iceweaselrc' is set to use padsp as the DSP
wrapper, a segfault occurs because the padsp script conditionally
sets environment variable 'PADSP_DEBUG' based on the presence of
the '-d' switch, but the code (padsp.c) unconditionally attempts
to read the value using 'getenv'.  The attached patch fixes the
script to set PADSP_DEBUG=0 if no -d switch was used.
