apache segfaults with pysqlite (again)

Some time ago I had problems with running pysqlite from mod_python and
every version beyond 2.0.6 was causing apache to segfault. Now I
upgraded several parts of my system including pysqlite but had no luck
the following combination

sqlite 3.3.5    (compiled with threadsafe enabled)
pysqlite 2.2.2
apache 2.0.53
mod_python 3.2.8
python 2.4

still makes apache segfault. The last couple of lines from running gdb
on the core file is:

and then a backtrace gives

So the situation is just the same as before, pysqlite version 2.0.5
works, but no version beyond that. Is there any more detail I could
send that would be useful for debugging this?
