Whilst experimenting with the Python bindings I noticed that exceptions

/etc/passwd : failed to parse.
However, there is no Traceback for the "raise". Is this correct?
import libxml2

You have
Python calling C calling Python.
the internal exception in the callback does not cross the C boundary
I don't see how this could work without disastrous side effects like
memory leaks or general instability in the program.
I don't think this is quite accurate. Think about python as a high-level
API to a C runtime. If the outer and the inner python runtimes are
the same, there is certainly a way to pass the necessary information through
(i.e. ultimately just preserve the exception state from the callback).
