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.

Workaround to avoid a crash in glibc

Avoid to descend into .debug directories. I just want to make you aware of this, feel free to reject it.
