possible when setting the timezone

Hello, I am developing an php application and by mistake a wrong timezone was
set after I initialized the connection, which resulted in a core dump of the
current process.
The postgres version is 8.0.3 running on a freebsd 6.0-RELEASE machine with
the generic kernel.
I tried searching for similar problems but I could not find similar reports.

from /var/log/messages:
