Other information:
We use objdump to split out the debug symbols and put them into
.debug/ORIGINAL_NAME. Now gst_registry_scan will recursively search
/usr/lib/gstreamer-0.10 and will find the .debug dir and start to scan it. This
will crash.

I have applied a patch to not descend into .debug directories, I will leave it
to you to accept or reject such workarounds as this bug is mostly in glibc.
