I have reported this to the Codeina devs first here:
https://core.fluendo.com/gstreamer/trac/ticket/217

The script gst-scanpackages (based on gst-python) scans a directory of rpm
packages containing gstreamer modules. It crashes if gst-python is in that
directory:

[goetz at n5 x]$ ls
gstreamer0.10-python-0.10.15-1mdv2010.0.i586.rpm
[goetz at n5 x]$ ../gst-scanpackages .
1736 blocks
Fatal Python error: PyEval_RestoreThread: NULL tstate
Abgebrochen

This happens as well in gst-python 0.10.16.

This is the gdb output:

(gdb) run ../gst-scanpackages .
