AWStats does not parse HTTP status 408 correctly from the log

[multiwebinc]

It appears that the version of Awstats Debian 7 uses is ancient, but it does not correctly recognize 408 HTTP status codes. Not sure if this has been fixed in more recent releases:

Error while processing /etc/awstats/awstats.conf
Create/Update database for config "/etc/awstats/awstats.conf" by AWStats version 7.0 (build 1.971)
From data in log file "/var/log/apache2/access.log"...
Phase 1 : First bypass old records, searching new record...
Direct access after last parsed record (after line 508)
AWStats did not find any valid log lines that match your LogFormat parameter, in the 50th first non commented lines read of your log.
Your log file /var/log/apache2/access.log must have a bad format or LogFormat parameter setup does not match this format.
Your AWStats LogFormat parameter is:
4
This means each line in your web server log file need to have "common log format" like this:
111.22.33.44 - - [10/Jan/2001:02:14:14 +0200] "GET / HTTP/1.1" 200 1234
And this is an example of records AWStats found in your log file (the record number 50 in your log):
192.243.55.129 - - [18/Jul/2016:02:28:21 -0400] "-" 408 0 "-" "-"
Setup ('/etc/awstats/awstats.conf' file, web server or permissions) may be wrong.
Check config file, permissions and AWStats documentation (in 'docs' directory).

I also tried with LogFormat=1 and I got a similar error.
