Crash report after update

[biggsy]

Every time I update to the latest snapshot for 2.1 a crash report is generated:

Crash report begins.  Anonymous machine information:

amd64
8.3-RELEASE-p8
FreeBSD 8.3-RELEASE-p8 #1: Wed May 29 17:31:57 EDT 2013     root@snapshots-8_3-amd64.builders.pfsense.org:/usr/obj.pfSense/usr/pfSensesrc/src/sys/pfSense_SMP.8

Crash report details:

PHP Errors:
[30-May-2013 17:57:20 Australia/Sydney] HTTP error, got response: HTTP/1.0 503 Service Unavailable

Filename: /var/crash/minfree
2048

Yes, that's it, one file of 5 bytes with 2048 and a line-feed  ???

When I try to submit the report Squid blocks it:

Invalid Request error was encountered while trying to process the request:

    POST /crash_reporter.php HTTP/1.1
    User-Agent: Mozilla/4.0 (compatible;)
    Host: crashreporter.pfsense.org
    Accept: */*
    Content-Length: 969
    Expect: 100-continue
    Content-Type: multipart/form-data; boundary=----------------------------898c2fd50f51

Some possible problems are:

    Request is too large.

    Content-Length missing for POST or PUT requests.

    Illegal character in hostname; underscores are not allowed.

    HTTP/1.1 "Expect:" feature is being asked from an HTTP/1.0 software.

Your cache administrator is admin@localhost.

I uninstalled Squid from that VM and it makes no difference.

Is the crash report submitted through the browser session and being blocked by Squid on the "production" pfSense?
