Thank you for taking the time to report this bug and helping to make
Ubuntu better. Could you specify which package version you're using?

I'm not 100% sure, but I guess I tracked down this problem to the fact
that my apparmor rules blocked access to /usr/share/zoneinfo , which
wasn't a problem with the older php packet versions. Nevertheless the
new versions shouldn't segfault coz the access was denied.

Hope this helps.

I was unable to reproduce this crash on karmic. Please re-open if you were and provide a testscript.
