[9.205][Bug] "web request blocked" with "Invalid argument"

ProKasro
We updated our ASG220 three days ago to Version 9.205-12. We have an internal web server (IIS 7 on Windows Server 2008 R2) that can be accessed from outside:

DNAT: Any -> HTTP -> EXTERNAL-ADDRESS
      Target translation: INTERNAL-ADDRESS
  
SNAT: INTERNAL-ADDRESS -> Any -> Any
      Source translation: EXTERNAL-ADDRESS

This worked very well until the last update. After this update we can not access the site with its external address from inside, we get following Errors:

2014:08:13-16:51:09 fw-prokasro-2 httpproxy[5833]: id="0002" severity="info" sys="SecureWeb" sub="http" name="web request blocked" action="block" method="GET" srcip="192.168.100.148" dstip="176.94.29.131" user="" statuscode="502" cached="0" profile="REF_DefaultHTTPProfile (Default Web Filter Profile)" filteraction="REF_DefaultHTTPCFFAction (Default content filter action)" size="2520" request="0x1074ea38" url="daten.prokasro.de/.../support" exceptions="" error="Invalid argument" authtime="0" dnstime="7" cattime="19332" avscantime="0" fullreqtime="55199227" device="0" auth="0" category="105" reputation="neutral" categoryname="Business"

and after configuring some exceptions for the domain daten.prokasro.de:

2014:08:14-08:45:18 fw-prokasro-2 httpproxy[5833]: id="0002" severity="info" sys="SecureWeb" sub="http" name="web request blocked" action="block" method="GET" srcip="192.168.100.148" dstip="176.94.29.131" user="" statuscode="502" cached="0" profile="REF_DefaultHTTPProfile (Default Web Filter Profile)" filteraction="REF_DefaultHTTPCFFAction (Default content filter action)" size="2520" request="0x15ef3278" url="daten.prokasro.de/.../support" exceptions="av,auth,content,url,mime,cache,fileextension,size" error="Invalid argument" authtime="0" dnstime="10" cattime="0" avscantime="0" fullreqtime="2424" device="0" auth="0"

From outside we have no problems.

     the automated download and unpacking process crashes the whole 220 system (as it always does).

    SA, this is not normal behavior.  I've never seen this, and you are, to my knowledge, the first person to report this problem here.  I bet there's some fundamental problem that might require reloading from ISO and restoring from config backup.

    Cheers - Bob
