Bug#798120: gstreamer1.0-libav: libgstlibav.so cause Libre Office segmentation fault

[Matt]

Package: gstreamer1.0-libav
Version: 1.4.4-2
Severity: normal

Dear Maintainer,

Trying to look at a .PPS file with Libre Office, libgstlibav.so probably causes a segmentation fault. 
It happens when Libre Office try to switch in full screen mode with sounds effects. 
Impossible to reproduce if .PPS is saved in .PPT format without automatic full screen switching and slideshow starting. 

Syslog tells this : 

Sep  5 20:00:12 montreal kernel: [ 1924.538567] wavparse0:sink[2364]: segfault at 2d8 ip 00007ffa32d3abd4 sp 00007ffa4a221460 error 4 in libgstlibav.so[7ffa32d21000+37000]

I have tried to install back gstreamer0.10-plugins-bad instead of gstreamer1.0-plugins-bad and the problem disappear with Libre Office (but others come back with Iceweasel). 

A but lost with these problems but may be help ? 
Thanks, 

Matthieu
