[Bug 306233] [NEW] Segmentation fault in timelib_builtin_db()

[ServerAlex]

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.
