Bug#735898: pavucontrol segmentation fault

[John M.]

The WorksForMe bug is certainly the worst of all.

At the time of reporting the bug, I had just moved to a new laptop, so
the issue happens on a newly installed Jessie.  In the old laptop (in
which Wheezy was originally installed in 2011), with all the Jessie
updates, pavucontrol has always worked without issue.

Since my home partition was cloned from the old laptop, I tried removing
~/.config/pavucontrol.ini and ~/.config/pulse/* and restarting the
session, with no success.  The only change in regards to pulse's default
configuration is "flat-volumes = no"  in /etc/pulse/daemon.conf, but
even reverting that one has no effect at all.

When running pavucontrol from the terminal I get:


        ...:~$ pavucontrol 
        Segmentation fault
        
        ...:~$ dmesg
        [elided iptables- and wlan0-related messages]
        
        [240126.731332] pavucontrol[16559]: segfault at 0 ip
        0000000000423177 sp 00007fffcc1e0630 error 4 in
        pavucontrol[400000+45000]
        

Since, for some reason, I have the murrine-themes package installed,
when running pavucontrol while using the Albatross theme, I get:


        ...:~$ pavucontrol 
        
        (pavucontrol:16963): Gtk-WARNING **: Theme parsing error:
        gtk-widgets.css:2597:41: Expected a valid selector
        Segmentation fault


I don't get any Gtk-WARNING when using the Bluebird or Greybird themes
(also from the murrine-themes package).

The binaries from other packages suggested by the pulseaudio one (i.e.,
paman, paprefs, pavumeter), work properly.

Is there any other information I can attach to the bug report?
