Basically maintaining a thread state variable along with the
global interpreter lock in the interface to the interpreter. It
appears to work when the Python interpreter is loaded from a
plugin (as panel applets or control modules would do), but has
problems from a Python program: for example, if you wrote a
PyKDE program that loaded a KPart, and the KPart later tries to
load the Python interpreter (which is already running) say to
load another plugin, thread state issues arise again. I haven't
been able to get back to that - the guys working on QtDesigner
plugins tried some of the obvious "fixes" but that didn't fix

The change is only in the later versions of PyKDE-3.8 (like the
one available at riverbankcomputing). The change only affects
libpythonize (PyKDE-3.8/pythonize. directory), so you could just
replace the version of libpythonize you're running now. That's a
very short compile (copy the source files from the newer
distribution, but use the older Makefile in the pythonize/
directory, and don't re-run build.py).
