Just a few minutes after posting to the list I found the fix.

I changed to apache2-mpm-prefork and now it seems to be working (at least no
segmentation fault).

Searching again the list archives I found some emails about that :)

I think this issue is important enough to be listed in pylucene's FAQ

Yours,
