Package: libgstreamer0.10-0
Version: 0.10.10-2
Followup-For: Bug #404876

EXECUTIVE SUMMARY: Due to a regression, any program that links
libgstreamer segfaults on G3 processors. I've fixed this by
recompiling libgstreamer from source. Everything works again.

DETAILS: Any program linked with libgstreamer-0.10 will crash with a
segmentation fault. This is most noticable when using Gnome which
requires gstreamer for many applications, however for simpler
debugging the problem can be replicated easily at the command line:

    $ sudo aptitude install gstreamer0.10-tools
    $ gst-inspect-0.10 
    Segmentation fault

Gdb and strace were not very enlightening so I compiled libgstreamer
from source like so:

    $ apt-get source libgstreamer0.10-0
    $ sudo aptitude install libgstreamer0.10-dev libglib-dev
    $ cd gstreamer0.10-0.10.10/
    $ ./configure
    $ cd gst
    $ make			# Go read a book, this will take a while

Using the newly compiled library makes the old executables work fine:

    $ LD_PRELOAD=.libs/libgstreamer-0.10.so.0.9.0 gst-inspect-0.10
    annodex:  cmmldec: CMML stream decoder
    annodex:  cmmlenc: CMML streams encoder
    halelements:  halaudiosrc: HAL audio source
    [...output truncated...]
    staticelements:  pipeline: Pipeline object

    Total count: 90 plugins, 279 features

Reinstalling libgstreamer into /usr/lib completely fixes this bug. All
applications, including the Gnome Desktop, work as they used to.

    $ strip .libs/libgstreamer-0.10.so.0.9.0
    $ sudo mv /usr/lib/libgstreamer-0.10.so.0.9.0 /usr/lib/libgstreamer-0.10.so.0.9.0.old
    $ sudo cp -a .libs/libgstreamer-0.10.so.0.9.0 /usr/lib
