I don't really what exactly is going on here, but in general extension
modules compiled for non-debug builds won't work with debug builds. The
Debian package is almost certainly fine.

Even if the maintainers do that, it won't help. Check that the module
works on its own with the regular Python build and then close the bug if
the maintainers don't beat you to it.

We still don't know what "it" is.
Strip down your script as much as possible. It looks like you're using a
lot of extension modules, and any one of them could (in theory) be
causing problems.
