Could you try getting the call trace from the core file ? Assuming the core file is in the current directory, you should do this:

$ gdb /usr/local/hobbit/server/bin/bb-eventlog.cgi core [messages from gdb] gdb> bt

The output from the "bt" command would be very helpful in narrowing down the problem.

Below is the output from gdb, I apoligize for the formatting, I'm using a rather awkward web client. Interestingly, I found that it runs fine as user 'hobbit', but users root and apache get a segfault.
