Hello,
Your Python is stripped (it does not have symbol information). This is a very bad starting point for an analysis we are going to undertake.
As I've alrady said, the problem is already solved in a way. Some of my external methods caused it (why they did it I don't know), but if you still think this might be a bug in Zope I'll give you the backtrace with debug information. Python is installed from source (from the FreeBSD ports collection).
Generate Python from sources and do not strip the binary.
OK.
I am also astonished that you are still using "libc.so.5". I had the impression that nowadays "libc.so.6" is installed everywhere.
Well, appearently this isn't the case with FreeBSD and we're running the latest 5.2.1-release. Thanks anyway, -Petter-
