#3371: RuntimeError: instance.__dict__ not accessible in restricted mode

In all probability, this is not a bug in Trac, but in either Subversion,
SWIG, or mod_python - I am filing this ticket principally so that there is
somewhere to collect reports of this problem, and make notes of any
debugging that is done.
I experience an '''intermittent''' Trac internal error, with the following
environment:
* Debian 'etch'
* SWIG 1.3.28-1.1
* Apache HTTPD 2.2.2
* Subversion 1.3.2 (using the above SWIG)
* mod_python 3.2.9-rc3
* Trac 0.10dev r3492

Some googling suggests that this error is a hint that a Python object
created in one subinterpreter is being used in a different subinterpreter.
This is supported by the fact that my Trac setup does indeed involve Trac
instances running under multiple subinterpreters.
