103.SEGV_table_get.patch

[Rob Hartill <ha...@ooo.lanl.gov>]

If you put mod_expires through enough hoops before using it, then
it can core dump by calling table_get with a NULL parameter.

103.SEGV_table_get.patch  to the rescue!

Changelog: another bug fix

Comments: modules probably need to do more error checking, but lets not core
          dump if they don't always.
