Lighttpd

I mistakenly added a mod_expire rule, using the incorrect keyword of 'year', instead of 'years'

Lighty fails to start, but outputs nothing to either screen or error log.
Icy talked me through this on IRC, and so here is gdb output he asked me to attach

/etc/lighttpd/lighttpd.conf (with mod_expire loaded)
-------------------------------------------------------------------
$HTTP["url"] =~ "^/js/" { expire.url = ("" => "access 1 year") }

Passing -D to lighty, results in "Segmentation fault"

Output from gdb...
--------------------
Starting program: /usr/local/sbin/lighttpd -Df /etc/lighttpd/lighttpd.conf

Program received signal SIGSEGV, Segmentation fault.
mod_expire_free (srv=0x92f2008, p_d=0x9305c50) at mod_expire.c:66
66 array_free(s->expire_url);

Cause
------------
"access 1 year" in config, should be "access 1 years"
Additionally, it seems any invalid param in expire url, causes a segfault

Expected Result
----------------
Parse error when loading config
