File/Function/line : webserver.c/ws_getheaders/631
Cause : Null pointer dereference. Any header that contains a line (not the first line) that does not contain a ':' will result in a null pointer dereference as strsep(&last, ':') will assign NULL to the variable 'last' and the code then attempts to dereference 'last'.
strsep(&last,":");

DPRINTF(E_WARN,L_WS,"Thread %d: Invalid header: %s\n",
pwsc->threadno,first);
